Why do scientists around the world use metric systems?

Answer 1

It is much easier and faster to use as it is based on 10. The English system or standard system is based on many diffrent numbers. Such as 12(in) or 16 (oz) or 3ft. (yard) I hope this makes some sense! :)

Answer 2

First, it is not just scientists. Most sensible people in most countries (Liberia, Burma,

and the US being the main exceptions) have adopted the System Internationale -

the international system of units. People use the SI units in daily life: buying foods

in kilograms, drinks in litres, etc.

Also, the relationships between large and small units for measures of the same

characteristic are all based on powers of ten. This makes conversion extremely

simple - unlike the Imperial system which required the use of many conversion

factors, for example:

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

12 inches in a foot

14 pounds in a stone

16 ounces in a pound

20 fluid ounces in a pint

22 yards in a chain

and so on and on and on ...

Furthermore, many of the derived units are so defined that the conversion from

measuring one characteristic to another is straightforward. For example,

1 cubic metre = 1000 litres;

1 Newton is the force required to accelerate a mass of 1 kilogram by 1 metre per second2;

1 Joule is the work done by a force of 1 Newton in moving the point of application through 1 metre; and so on.
