Weight and Mass

Weight and mass are two commonly misunderstood terms in fluid mechanics and mechanics. Weight is the measurement of the gravitational force on an object, while mass is the measurement of the amount of matter in an object.

How many grams are in a kilogram?

There are 1,000 grams (g) in a kilogram (kg) and 0.001 kilogram equal a gram. The prefix "kilo" (symbol k) in the International System of Units (SI), means one thousand.
1,000 grams in a kilo.
1 kg = 1000 g
1 kg = 1000 grams

1 gram = 0.001 kg

How much is 150 pounds in kilogram?

150 pounds is equal to 68.0388555 Kilograms.

1 Pound = 0.45359237 Kilograms

150 Pounds * 0.45359237 Kilograms = 68.0388555 Kilograms.

Algebraic Steps / Dimensional Analysis Formula 150 lb*1 kg

2.2046 lb=68.0388555 kg

How many pounds are in a kilogram?

One lb is 0.454 kg, so a tad more than 2.

1 kilogram = 2.2 pounds. (2.20462262 to be more precise).

22 pounds = 10 kilos

The formula to convert kg to lbs

1 kg * 2.2046 lbs

= 2.204622622 lbs

kg and lbs can't be equated, since they're units of different types of quantities.

The "kg" is a unit of mass, whereas the "lb" is a unit of force.

On Earth, 1 kg of mass weighs 2.205 pounds. In other places, the same 1 kg

of mass has a different weight.

Formula: pounds x 0.454 = kilograms

How much does one gallon of water weigh?

Weight of 1 US Gallon of water = approx. 8.35 lb (about 3.785 kg)

Weight of 1 Imperial gallon (i.e. UK measure) of water weighs 10 pounds (4.536 kg) by definition, at a specified temperature and pressure.

How many pounds is 100 Kilograms?

100 kilograms = 220.462262 pounds

1 kg is equal to 2.2046 pounds. If you multiply 100 by 2.2 the answer is 220 pounds, or more precisely 220.4623 pounds.

What is the ideal weight for a 47 year old female that is 5'9?

For a medium frame allow 100-102 for the first 5' in height and 5 lbs per inch thereafter

So, 5'9" female should weigh 145-147 lbs.

How much does a cubic yard of gravel weigh?

A cubic foot of dry, loose gravel with 1/4" to 2" stones is 105 pounds per cubic foot. So, a cubic yard is that times 27, or 2835 lb. (There are 27 cubic feet in a cubic yard.)

How much does sea water weigh per cubic foot?

The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot.


The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.

How do you convert litres into pounds?

There is no equivalence.

A pound is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a litre of air. How many pounds? Next consider a litre of water. How many pounds?

The masses of equal volumes of the two substances will clearly be very different.

There is no direct conversion between mass and volume:

You need to know the density of the substance to enable you to carry out the conversion.

If you can find the density of the substance (grams) then to convert the amount of litres to pounds:

  1. Convert it to kilograms to maintain the same unit
  2. Multiply the number of kilograms by 2.20462 (pounds/ kilogram)
  3. The result will be the amount of litres of the substance in kilograms

How many kilograms are in one pound?

It is equal to 0.454 kilograms approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply pound by 0.4535 to get the equivalent kilograms.

What is mass divided by weight?

Answer #1:

It's (1) divided by (the acceleration of gravity in the place where that mass has

that weight):

weight = mass x g (where g is the acceleration due to gravity)

⇒ mass/weight = mass/(mass x g)

= 1/g

On the earth, g ≈ 9.81 ms-2 ⇒ mass/weight ≈ 1/9.81 ms-2 ≈ 0.102 m-1s2

On the moon, g is approx 1/6 that of the earth, ⇒ mass/weight ≈ 6/9.81 ms-2 ≈ 0.612 m-1s2

If the questioner really meant weight divided by mass it gives the acceleration

due to gravity in that place otherwise I'm not sure of a use of knowing the

reciprocal of the acceleration due to gravity that the questioner asked.


Answer #2:

If you ask a scientist, that's true answer in the sense that a mass M experiences

a gravitational force Mg and if you measure weight in units of force (which

nobody does). But anyone else would be surprised to learn that a mass M (say

10 grams) would have a weight of anything else but M grams (10 grams).

Sometimes expressed as "grams weight" often just grams for short. If you pick

up a Kilogram, even a scientist would say "its weight is 1 kilogram". The

gravitational force on it is 1g, so if you let it go it will accelerate at a rate force

over mass, which is g. So the answer depends on your units of mass and weight.

That's why science lessons tend to avoid use of "weight". In outer free space

mass would be measured by (say) tension in the string if you whirl it on the end

of it around your head, but the weight (measured by a spring balance) would be

zero (precisely as described in the first answer above, with g=0).


Answer #2.1:

The problem with discussing mass and weight in the same units, and the reason that this masked contributor is waging a one-man battle to make the distinction recognized and acknowledged by users of this website, is the new problem that

you have now that the space age is here.

As long as we were all irrevocably bound to the Earth, one kilogram of mass would always weigh one kilogram, if you like it that way. We could afford to be sloppy about it, with hardly one out of ten men-on-the-street knowing or caring about the difference, and nobody ever had a problem with it.

But now that some of us have already slipped these surly bonds ... and among

the general population, the younger you are, the better the chance that you will

do so one day before you're done ... those who ignored the distinction begtween

mass and weight all through school, or never even encountered it there, are

poised to step into an inconvenient pile. Because as soon as you pack for your

trip to anywhere else away from Earth, and take along your lucky kilogram,

you're due for a shock when you step out at your destination: Your kilogram

doesn't "weigh" a kilogram there. It weighs something else. If you're on the

moon, for example, your kilogram weighs 0.165 kilogram ! That's the

shock I'm trying to avoid, because if you think the straight dope is too complex

for people to handle now, you haven't seen anything yet.
