What do metric measurement use?

Metric measurement uses a decimal-based system that includes units such as meters for length, kilograms for mass, and liters for volume. The metric system is organized into prefixes that denote multiples or fractions of these base units, such as centi- (one hundredth) and kilo- (one thousand). It is widely used around the world for scientific, commercial, and everyday measurements due to its simplicity and consistency.
