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!]

Most scientists use the Metric system of units of measure, also called the Système international or SI system

They use the SI units, so they can compare conclusions in their experiments, and understand each other. Instead of using different types of measurements, they can't understand, they use the same.

SI units are standardized among most countries which allows measurements done in one to be valid and reproducible in any other participating country. Not all countries use there units, most noticeably the USA and Great Britain.

The SI unit is the Kelvin, but we use Celsius a lot too.

Standard International (SI). It is the modern form of the metric system.

Most scientists use the Metric system of units of measure, also called the Système international or SI system

Scientist do use the metric system, they may refer to it sometimes as the SI system. Only three countries in the world haven't fully converted to metric, Liberia, Myanmar(Burma), and U.S.A, and even in these countries most scientist use the SI system.

Scientists use the metric or SI units of measurement.

The world system of measurements units is based on the metric system (SI).

The version of the metric system that modern scientist uses is called The International System of Units or SI.

My Dad is a scientist and i asked him- he saidthe SI system...

Yes The metric, or SI, system is used by scientists in every country.

There are national and international standards for measurements. In America it is the ANSI system, in Europe it is SI.

It was recognised that there needed to be an internationally common scientific measurement system and the international scientific community concensus was that it should be the SI system.

The system of units scientist use to measure the properties of matter are the SI units.

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.

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.
