How do you convert SI units?

Answer 1

Multiply or divide by powers of 10.

SI units are easy to convert because you multiply or divide by 10 - sometimes more than once. Think of a staircase - every time you step up a stair, you divide by 10; every time you step down a stair, you multiply by 10.

Another way to think of it is: as you move down the staircase, the decimal moves to the right; as you climb up the staircase, the decimal moves to the left.

If you need to memorize the order of the prefixes, there are a number of mnemonics that can help you. My personal favorite is "King Henry Dropped over Dead Converting Metrics."

To convert between SI units, you can use conversion factors. Multiply the quantity by the conversion factor to change units.
