SI Prefixes Unit Conversion Table - Tutorial

SI Prefixes Unit Table - Definition, Example

Definition :

SI stands for 'International System of Units' Metric or SI units allows conversion from one set of units to another. It is based on the units of ten. All units of a particular measurement in Metric conversion are derived from the corresponding base unit by adding up some metric prefix.

Metric Units :

yotta(Y), zetta(Z), exa(E), peta(P), tera(T), giga(G), mega(M), kilo(k), hecto(h), deka(da), deci(d), centi(c), milli(m), micro(µ), nano(n), pico(p), femto(f), atto(a), zepto(z), yacto(y) .

Example :

The distance from City A to City B is 8.0 x 103 meters. From the above table, 103 can be replaced with the prefix 'kilo'. Now the distance could be stated as 8.0 kilometers or 8.0 km.
