Units, prefixes and conversions


A measurement is not complete without its units: 20 meters is meaningless without the meters (m). Some measurements are very small, or large, and require smaller or larger versions of the unit. It is important to convert between units when a smaller or larger unit is more appropriate.
Read this page to learn about different sized units, the prefixes that identify them, and how to move from one to the other.
