How do you convert from the English system to metric?

Answer 1

English system and SI (metric) have many different units; you have to know what you want to convert, and look up the specific conversion. Quite often, you will want to convert lengths; 1 in. is exactly 2.54 cm. (0.0254 meters); one mile is about 1.6 km.

Answer 2

It all depends on whether you're converting length, area, volume, force, weight,

power, speed, acceleration, or energy. You need different numbers to convert

each of those.

In fact, there are several different numbers for each one. For example, if you want

to convert a length, you need different numbers to start with inches, feet, yards, or

miles. That's the beauty of the English system !
