Metric Prefix Converters

The metric system is a system used to measure length, weight, and volume. The most common measurements are meters for length, grams for weight, and liters for volume.

All the metric measurements use the same prefixes, for example kilo in kilograms and kilometers, or centi in centimeters and centiliters.

Regardless of what kind of metric measurement it is, the prefix ratios are the same. For example, the ratio of hectoliter to deciliter is the same ratio as hectogram to decigram.

There are 20 of these prefixes: Yotta, Zetta, Exa, Peta, Tera, Giga, Mega, Kilo, Hecto, Deka, Deci, Centi, Milli, Micro, Nano, Pico, Femto, Atto, Zepto, and Yocto.
