The metric system is a system of units for measurement developed in late 18th century France by the chemist Lavoisier to replace the disparate systems of measures then in use with a unified, natural and universal system. Its symbol is given by ‘mol’. The current international standard for the metric system is the International System of Units (Système international d'unités or SI). Introduction to Measurement SOL 6.9 By: Jennifer Del-Castillo John F. Kennedy Middle School What you need to know First things first, you need to understand the basics There are two systems of measurement US/Customary System which we use here Then there is the metric system which is used all over the world Measurement … There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd). The metric system uses units such as meter, liter, and grams to quantify length, volume and weight, as the U.S. customary system uses feet, quarts, and ounces to measure them. His unit of length, the “standard”, was the length of a pendulum that had a half-beat of one second, the units of area and volume were the square and cubic standard respectively and the unit of mass was the mass of a cubic standard of rainwater. One group of units used to measure items such as length, temperature, time and weight is known as the metric system.
