The metric system, also known as the International System of Units (SI), is a widely used system of measurement that is based on the decimal system. It is used in almost every country in the world and is the standard system of measurement in science, technology, and international trade. In this article, we will provide a comprehensive guide to the metric system, including a printable chart and conversion tables.
History of the Metric System
The metric system was first introduced during the French Revolution in 1791. It was developed by a committee of scientists and mathematicians who were tasked with creating a new system of measurement that was based on the decimal system. The system was designed to be simple, logical, and easy to use, and it was intended to replace the many different systems of measurement that were in use at the time.
Over the years, the metric system has undergone several changes and revisions. In 1960, the International Committee for Weights and Measures (ICWM) was established to oversee the development and implementation of the metric system. The ICWM is responsible for defining the fundamental units of measurement and for ensuring that the system is consistent and accurate.
Basic Units of Measurement
The metric system is based on seven fundamental units of measurement, which are used to measure different physical quantities. These units are:
- Meter (m) - unit of length
- Gram (g) - unit of mass
- Liter (L) - unit of volume
- Second (s) - unit of time
- Kelvin (K) - unit of temperature
- Ampere (A) - unit of electric current
- Mole (mol) - unit of amount of substance
These units are used to measure a wide range of physical quantities, including length, mass, volume, time, temperature, electric current, and amount of substance.
