# Why do scientist use si system of measurements?

SI stands for the French système international. It is basically the international system

of units. The system was created to be a coherent consolidation of all the forms of

measurements. Because it is a universal system used by everyone internationally (except

Liberia, Myanmar, and the USA) it means conversions are usually not necessary.

Conversions between units also become easier because the system was designed

that way (notice how factors are nearly always powers of 10).

Si units are universal and are based on factors of ten, making conversion a lot more simple. There are only three fundamental units (meters for distance, kilograms for mass, and seconds for time) and these are the only units used per property. The only difference would be the prefixes changing (for example centimeter, kilometer, milligram).

The SI measurement system has commonly agreed upon definitions, and agreed derivations for other than the primary defined ones.

The units defined are Metre, Kilogram, Second, Ampere, Mole, Candela.

It is not uncommon to have errors in complex structures because of a mix of units.

[Locally, one person worked out in oF the expansion of the bridge beams, and the other folk thought the degrees were Celsius, and worked out their expansion joints accordingly. Very expensive!]

It is simple, convenient, and internationally agreed - except for a few countries (USA, Liberia and Myanmar) that are still stuck with their primitive systems.

### What are the units used for Si?

SI units, which is the abbreviation for International System of Units, is used for making measurements that can be understood in various countries. While most countries have no adopted SI units as their form of measurements, some countries like the United States only use them in certain areas of study.

### Does the us use Si measurements?

Sort of. US measurements are now for the most part defined in terms of SI units. Also, a few SI units such as "seconds" are used directly.
