The following table of 24 SI prefixes ranging from 10 30 to 10 −30 are currently recognized for use. Prefixes. The simplified table below shows common metric prefixes and the relationship with their place values.
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol.
This table of metric prefixes has the standard names for each prefix used in science and measurements. It also shows the symbol used to represent these prefixes, their ‘power of ten’ and the number you are actually replacing with the prefix.
Metric system prefixes provide a simple way to understand exactly what each unit of measurement stands for in the metric system, since the prefixes tell you how much bigger a unit is than the base unit. Take a look at the most commonly used metric prefixes for length, mass, volume, and time.

The International System of Units (SI) is made up of 7 base units, featured on this chart with their Measurement League counterparts. The SI, commonly known as the metric system, is easy to use.
Table of metric system prefixes, symbols, and multiplication factors. The metric system defines prefixes and corresponding symbols for positive and negative powers of 10, as applied to each unit of measure.
Prefixes. Some of the metric units listed above include prefixes such as kilo, centi, and milli. Prefixes, added to a unit name, create larger or smaller units by factors that are powers of 10. For example, add the prefix kilo, which means a thousand, to the unit gram to indicate 1000 g; thus 1000 g become 1 kg.
Metric Prefixes. A metric prefix precedes a unit of measurement and indicates a multiple or fraction of that unit. For example, kilo may be added to metre to indicate 1000 metres, i.e. there are 1000 metres in a kilometre (km).
The abbreviation SI is from the French language name Système International d’Unités (also known as International System of Units). Twenty SI prefixes are used to combine with units of measure. For example, the prefix name kilo, which equals 1,000 denotes a multiple of one thousand, as exemplified by: 1 kilometer = 1,000 meters.
