what is the metric system

The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively. It is a decimal system, which means that its units are based on powers of ten. The metric system was designed to have properties that make it easy to use and widely applicable, including units based on the natural world, decimal ratios, prefixes for multiples and sub-multiples, and a structure of base and derived units. The metric system is used worldwide in calculations and research. It is an easy-to-use measurement system as it has units in terms of powers of 10. The metric system is also known as the International System of Units (SI), which is the current international standard for the metric system.
