Why is it easier to convert SI units than the English system of units?
There are several reasons why SI is preferred to the old English system of measurement: SI is not based on the arbitrary construct of the human body; rather, on precise and definite standards. SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units.
Why do scientists prefer SI units?
SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units. SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.
Who uses English units?
Only three countries – the U.S., Liberia and Myanmar – still (mostly or officially) stick to the imperial system, which uses distances, weight, height or area measurements that can ultimately be traced back to body parts or everyday items.
