In the metric system, converting from one prefix to the next prefix is a simple matter of multiplying or dividing by 10. Note that this does not work when the units are squared (2) or cubed (3) as in area and volume measurements. When the prefixes get smaller, multiply by 10 for each step. × 10 × 10 × 10 × 10 × 10 × 10 × 10
mega- kilo- hecto- deca- no prefix deci- centi- milli-
When the prefixes get larger, divide by 10 for each step. ÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10
mega- kilo- hecto- deca- no prefix deci- centi- milli-
