Because it is a SYSTEM and was designed for ease of use. The accumulation of English-Imperial-American-Customary units is not a system. Example. A cubic inch of water weighs what? Versus- a cubic cm or water is a ml and weighs one gram. The best way to get to know the metric system is to NEVER covert units from inches, etc. Just use metric--it's simple! Conversion are hard and a huge bother. Science has used the metric system for a couple centuries. Many important units are defined in metric terms and nothing else.
The ease of calculations and unit changes come from the SI systems standardization of derived measures. SI units include the the kilogram, liter and Newton. Changes are simplified as units can be cancelled out in equations, and there is no need to convert to other measures such as US/Imperial.
Because for most things all you need to know is the 10 times table which, given the fact that we use the decimal system for counting, means that all you need to know is how and when to move the decimal point to the left or right. Or, equivalently, change the prefix for the name of the unit.
With the Imperial system you need to know the tables for
2 Pints to Quarts
3 Yards to Feet
4 Quarts to Gallons
8 Pints to Gallons
12 Inches to Feet
14 Pounds to Stones
16 Ounces to Pounds
20 Fluid Ounces to Pints
and many others.
The SI system is used by almost all countries in the world, for most all types of measurement. If you have a crack at SI in wikipedia you'll see it is so.
Even in the US, the metric system of measurements has been legal for a long time, even if not widely used.
There are some exceptions however, such as in the weight of precious stones, or of the purity of gold.
It eliminates ambiguity (if someone says "miles", do they mean US statute miles? Nautical miles? Imperial miles? Something else?) and the fact that the units are (almost) all based on the decimal system makes it trivial to convert from larger units to smaller ones (compare miles: there are 8 furlongs in a mile 40 rods in a furlong, 5.5 yards in a rod, 3 feet in a yard, 12 inches in a foot... it's a ridiculous series of conversion factors to memorize).
I was asking the same thing but i think its easier for scientists because they could communicate with other scientists in the world without to much confusion.
because everything is based on the power of 10. the measures all realate to the number 10. and the prefixes
SI units are more accurate than English system units
Results obtainned from various scientific works are to be accepted world wide. SI UNITS are internationally accepted units. so, every scientific works are done in SI unit.
Well, Its Not Really Easy Its Probably Because Your Good At Converting In The Metric System's . You Are probably Ahead Of Kids To Make It easy For You.
The metric system, also known as the SI system of units, is the system most typically used in the science community.
The SI (Systeme International) units have made scientific calculations easier.
The SI unit for temperature is Kelvin.Kelvin = Celsius + 273Fahrenheit and Celsius are non SI units, however, Celsius is used in science as it is so easily converted to Kelvin.
If you wish to know about the names and types of science dimensions, then have a crack at SI Units in Wikipedia.org
inches,volume,temp,mass,density,time
SI units are more accurate than English system units
The International System of units (SI units)
It's arbitrary, but is current practice.
SI units are used in Science Classes because they are universal and standard, and they are also easier to use because they are based no the power of ten.
SI is the system of standard units used in science. An abbreviation for Systeme Internationaland and is the basis of the metric system.
It depends on the science.Most science normally uses the SI (international system) - the same system which is used in most countries of the world in everyday life as well. Theoretical particle physics often uses another system, called the system of natural units, or Planck units. Many sciences use at least SOME non-SI units; for example, in particle physics, even if the SI is used most of the time, energies are usually expressed in eV. And in most areas of science, non-SI time units (i.e., units other than seconds) are used.
The same units can be used for any type of energy - and in modern science, the same units ARE used. For example, the SI unit for energy is the joule.
In science the International System (SI) of unit is used. This is a metric system.
a system of measurement for science, industry and commerce
because it shows the measurements in physical science
The metric system, also known as the SI system of units, is the system most typically used in the science community.
In engineering and science, a system of units called SI is used. The same units are used worldwide in most countries outside of the United States, except that in practice, some non-SI units are used as well (for example, hours and days instead seconds, and the degree Celsius instead of Kelvin).
