Metric System

The metric system is an international basis of measurement based on a decimal system. It uses standard base units to name larger and smaller units.

2,771 Questions

How big is 20mm in inches?

These are the units of length, SO ,we need to find out the relation between both these units.mm and inchese are related to each other as follows :

1 inches =25.4 mm.

which means 1 mm=0.039 inches .

Now,2 mm=2 * 0.039 inches .

the result is 0.078 inches.

What is the density of 350 grade steel?

350 grade steel typically has a density of around 7.85 grams per cubic centimeter.

Why do you need a metric system insteed in an English system?

You don't. The metric system is the international system of measurement. It was designed with several goals in mind. Neutral and universal Any laboratory can make a model of the base units. Starting with length, the meter was determined by the distance between two lines of latitude. This can be measured at any location on earth with the proper instruments. Once the length is established, a cube can be constructed that is 1/10 km on each edge. The volume of this cube is the liter. Everyone has access to water, so fill this cube with water and you have a kilogram of weight at 3.98 degrees celsius. Oh, yes, you also had to develop a thermometer by dividing the difference between water's freezing and boiling points into 100 equal parts. Decimal multiples The metric system is decimal. The next larger unit is always 10 times as large, the next smaller always 1/10 as large. You don't have to remember 12 inches to a foot, 3 feet to a yard, are there four pints in a quart or only two, etc. To convert, simply move the decimal point. Prefixes All derived units use a common set of prefixes for each multiple. "Kilo" means 1000 whether it is used both for mass (kilogram) or length (kilometre). A few units such as the tonne (megagram) and quintal (100 kilograms) survive from old units but have been rounded to metric. The prefixes which come from the Greek language (kilo, mega, giga) are multipliers and those with Latin origins (centi, milli) are divisors.

How many grams equals on ton?

1 standard ton is 2240 lb = 1016 kg = 1,016,000 grams
1 mt = 1000000 g

10.5 cm in equal to how many inches?

Inch and cm are used for measuring the distances. To convert the centimeters to inch we have to multiply the cm unit to 0.393701. This will convert the distance from cm to inch. The answer to the above question is 4.1338 inches(approximately).

How do you convert meters into mile?

-- Divide the number of meters by 1.609344

OR

-- Alternate (your choice): Multiply the number of meters by 0.62137

-- Either method gives you the distance in miles.
There are 1609.344 metres in one mile. Therefore, to convert metres to miles, divide by 1609.344.

What is the square meter of a rugby field?

Rugby union max 100 x 70 = 7000 m2. Rugby League 100 x 68 = 6800 m2
IRB regulations state that a playing area shall be no less than 70 metres wide by 100 metres long and an in-goal area on each end of the pitch of not greater than 22 metres in depth

What does kph mean?

KPH stands for kilometers per hour, which is a unit of measuring speed or velocity in the metric system. It represents the distance traveled in kilometers in one hour.

What is the abbreviation for Dekagram?

The abbreviation for decameter is "dam", since the abbreviation of deka is da and the abbreviation of meter is m.

Ross is 94cm tall.Dee is 37cm tall how tall is Dee in meters and centimeters?

Dee, who I am assuming is either a large llilyputian (From Gulliver's Travels), a small midget, or a baby, is very short. Dee is only 37cm tall, which is equal to 0.37 meters. That equals only 14.5669291 inches.

Wow.

Which unit is commonly found only in the Metric System?

The metric system uses kilograms, seconds and meters. Meters is a measurement typically used only in the metric system.
Some units in the metric system are meters, centimeters, millimeters, and liters.

9 pound 6 in kilograms?

To convert pounds to kilograms, you can use the conversion factor 1 pound is approximately 0.453592 kilograms. So, 9 pounds is approximately 4.08233 kilograms. Converting 6 inches to kilograms is not a valid conversion as inches are a unit of length, not weight.

Differentiate English measurement and metric system?

The metric system is easy to learn and remember as it is based on a count of 10 100 and 1000's etc. (10 mm's. in a centimetre, 1000 centimetre in a meter etc.) Compared to the metric system I can't think of any good points with the English system of measurement.

How many mcg tables equal 1 mg tablet?

Answer #1

How many mg in 1 mcg? The answer is 0.001.

mcg is 1 millionth of a gram. mg is the symbol for milligram, 1 thousandth of a gram.

For example:

100 micrograms = 0.1 milligram

1000 micrograms = 1 mg

Answer #2ERROR! ------ 1 MCG IS not "1 millionth of a gram", AS STATED ABOVE.

1 mcg is one THOUSANDTH of a gram. One Thousand mcg equals One milligram.

Answer #3Nope, the first guy is right (answer #1). Your confusion (answer #2) is probably because
  • "milli-" means a thousand parts, NOT a million parts.
  • "micro" is a million parts

This may seem counter-intuitive because "milli" is pretty close to "million", but the nomenclature doesn't work exactly the same with small parts.

Another reason you are making this mistake is a "milli-" of something, gram in this case, is written out as 0.001 which intuitively seems to be more like 100 than 1,000 parts. All of this stems to the very beginning of the SI prefix chart.

If we start with the number 1 and move the decimal place one to the LEFT, we get a "deca-" and it is shown as 10. If we instead move the decimal one to the RIGHT we get 0.1, NOT 0.01. That is where your brain is confusing everything. Just remember the decimal is one place less than you think it is when you go smaller than 0. So centi- is a hundredth so we might think it is 0.001 when actually it is 0.01. And nano- is a billionth, but it is not 0.000 000 000 1, it's 0.000 000 001.

1 mcg is NOT a thousandth of a gram.

1 mcg = 1 microgram = 1 µgram

1 mcg = 1x10-6 grams = 1/1,000,000 gram = 1 millionth of a gram

To further clear up confusion, it may be beneficial to have comparison benchmarks:

100 n/a n/a One

10-1 d deci- Tenth

10-2 c centi- Hundredth

10-3 m milli- Thousandth

10-6 µ (mc)micro- Millionth

10-9 n nano- Billionth

10-12 p pico- Trillionth

10-15 f femto- Quadrillionth

10-18 a atto- Quintillionth

So using chart above which is RIGHT, we can see the first guy takes the difference of

g --> µg (mcg) (the "g" is the SI abbreviation for "gram")

1 of 100, which is 1.

And 1 of 10-6, which is .000001

Take the difference (6-0=6) and there is 1x10-6 or 1 million parts composing 1 part of the gram.

To get to thousands to millionths

milligrams --> micrograms

mg --> µg (mcg) (the "g" is the SI abbreviation for "gram")

m --> mc

1x10-3 --> 1x10-6

Take the difference (6-3=3) and we find there is 1x10-3 or 1 Thousand parts composing 1 part of the milligram.

Basic unit of volume in metric system?

In the International System of Units (SI), the metre (American spelling: meter) is the base unit of length. Since volume is based on length × width × height, the basic unit of volume is based on the volume of a cube with sides of 1 m.

1 m × 1 m × 1 m = 1 m³ (cubic metre)

However, in common usage, the cubic metre is too big for most needs. The litre (American spelling: liter) is defined as 1 cubic decimetre. A decimetre (dm) is 0.1 m (or 10 cm). That is, the volume of a cube with sides of 10 cm.

A litre has the symbol: L

1 L = 1 dm × 1 dm × 1 dm

= 10 cm × 10 cm × 10 cm

= 1000 cm³ (cubic centimetre)

This also means that the cubic centimetre is equal to 1 millilitre (mL). There are 1000 litres in a cubic metre, meaning that 1 cubic metre is equal to 1 kilolitre (kL). That is:

1 mL = 1 cm³

1 L = 1 dm³

1 kL = 1 m³

For American readers, a liter is slightly larger than a quart.

Possible units for measuring mass in the metric system?

The metric system has two commonly used measures of mass. The first is the gram (g), and the other is the SI standardized unit of kilogram (kg). 1000 g equals 1 kilogram, and 1 g is .001 kg. Mass is the amount of matter in a sample, and it should not be confused with weight, which is a force (F). The SI unit for F is derived through mass is the Newton (N).

Defend the use of the metric system?

There are several advantages. Some of them are:

1. They are internationally agreed as standard. Not like a gallon which can mean one amount in the US and another in the UK.

2. Orders of magnitude for the same measure are related by simple decimal (multiples of ten) conversions and only a handful of prefices are required (although there are a lot more). By way of contrast, the Imperial system uses:

  • 2 pints in a quart
  • 3 feet in a yard
  • 4 quarts in a gallon
  • 6 feet in a fathom
  • 8 furlongs in a mile
  • 9 square feet in a square yard
  • 12 inches in a foot
  • 14 pounds in a stone
  • 16 ounces in a pound

and so on, and on and on. The decimal structure also makes it very simple to use scientific notation for small and large quantities.

3. It is used by most people in the world. The main recalcitrant countries are USA, Liberia and Myanmar. Even in the US, scientists normally use SI. When they don't they have disasters like the one that trashed NASA's Mars Climate Orbiter!

4. There are many simple relations from measures for one characteristics to another. For example, the SI unit of length is 1 metre. 100 square metres = 1 are, the unit for area. 1 cubic metre = 1000 litres, the unit for volume.

I would have great difficulty finding one line of defence for the Imperial system.

What does a metric ruler look like?

A metric ruler is a straight tool typically made of plastic, metal, or wood with markings in centimeters and millimeters. It is usually 30 centimeters long (or 12 inches), with smaller divisions for millimeters marked along its length. The markings are used to measure length or distance accurately.

What is the difference between the metric system and ours?

This depends on what country you mean by 'ours'!

In the UK they have been using what is known as Imperial measures for centuries for many things. These measurements have become standardised over the centuries.

They have feet and inches, miles and gallons, ounces and pounds and stones! How strange!

Metric measures have names like litres, metres, centimetres, millimeters, etc.

One measure of length in the UK is a 'foot'! Although originally based on an average length of someone's foot (!), it is equal to approx 0.3048 of a metre. (= metric)

Whereas Imperial measures have become established by custom and usage, metric measures are based on physics (with, perhaps, some relationship to features of the earth).

For example the 'metre' was originally designed to represent 1⁄10,000,000 of the distance from the equator to the north pole through Paris.

However, to be even more precise, it is now defined as the distance travelled by light in absolute vacuum in 1⁄299,792,458ths of a second!

This is tricky to check by yourself, so it best to just accept the current definition!

The metric system has the advantage that calculations are made easier because every metric unit is based on multiples of ten, whereas Imperial measures have different multiples. For example, a foot has twelve inches (not ten toes!), and three feet equals a yard (not a tripod!).

However, the metric system still has it's own limitations. Just try dividing 1 by 3 on a calculator! But what is 1/3rd of a 'foot'? Exactly 4 inches of course!

How many grams does it take to make an ounce?

The international avoirdupois ounce has 28.349 523 125 g.

The troy ounce is 31,103 476 8 g.

But bear in the mind that ounce is an old, non SI unit and must be avoided.

For example, federal taxes on fermented liquors are based on a barrel of 31 gallons; many state laws fix the "barrel for liquids" at 311/2 gallons; one state fixes a 36-gallon barrel for cistern measurement; federal law recognizes a 40-gallon barrel for "proof spirits"; by custom, 42 gallons compose a barrel of crude oil or petroleum products for statistical purposes, and this equivalent is recognized "for liquids" by four states.

3. "Struck measure" refers to a struck, or level, bushel. It is the only official bushel measure in the UK.

4. Frequently recognized as 11/4 bushels, struck measure.

5. Used in assaying. The assay ton bears the same relation to the milligram that a ton of 2,000 pounds avoirdupois bears to the ounce troy; hence the weight in milligrams of precious metal obtained from one assay ton of ore gives directly the number of troy ounces to the net ton.

6. The gross or long ton is used commercially in the United States to only a limited extent, usually in restricted industrial fields. These units are the same as the British "ton."

In what year did Australia begin to change the metric system?

14th February 1966 was the date for the conversion of Australia's currency from Pounds, Shillings and Pence, to Dollars and Cents.

The conversion to Metric for units of measurement was completed for most usages during 1974.

The change to Metric measurement conversion was commenced in 1969, and was completed in 1988. The conversion was done slowly because of the cost to many industries, and the need to "tool up" for it.

For example, cars were built with some metric changes in 1974, such as speedometers in both kilometres and miles.

Odometers in these speedos read in kms, but the speedometers read in both kilometres per hour and miles per hour.

By 1976, all newly-manufactured road-going vehicles were required to have speedometers with all metric readings and markings, and older vehicles were encouraged to have their speedometers changed to metric.

There was a roaring trade in speedometer conversions for a few years.

The fasteners used in manufactured items such as motor cars were changed slowly, with many Australian-built items, using a mixture of metric and imperial fasteners from the late 1970's to the mid-1980's.

The WB model Holdens for example (built 1980-1985), were mostly imperial fasteners from the front door pillars back, but the front section from the firewall forward, used metric fasteners.

This mixture of fasteners leads to problems in re-assembly, if care isn't taken, and the thread type must be checked carefully.
