# What is the meaning of SI in chemistry?

The International System of Units (SI) is system of units of measurements that is widely used all over the world. This modern form of the Metric system is based around the number 10 for convenience. A set unit of prefixes have been established and are known as the SI prefixes or the metric prefixes (or units).

A French lesson! S.I. is an abbreviation of Système Internationale or International System: our metric system of measurements. It is an internationally standardised system, giving a common language between nations and between the different branches of science and technology.

Likewise, why do we use SI units? SI units are interrelated in such a way that one unit is derived from other units without conversion factors. SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.

### What are the advantages of SI units?

The greatest advantage of SI is that it has only one unit for each quantity (type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize. For example, the one and only SI unit of length is the meter (m).
