Frequently asked questions
What is the easiest way to convert units?
Multiply by a conversion factor written as a fraction equal to 1, such as 12 in / 1 ft, so the unwanted unit cancels.
Why is the metric system easier?
Every metric unit is a power of 10 from the next, so conversions only move the decimal point.
