Metric System

Sistema Métrico

Definição

Sistema internacional de medição baseado em decimais, construído sobre sete unidades de base do SI, adotado oficialmente por todos os países exceto Estados Unidos, Myanmar e Libéria.

Explicação

France introduced the metric system in 1799, initially defining the meter as one ten-millionth of the Earth's quadrant. The system's power lies in its decimal structure: converting between units requires only multiplying or dividing by powers of 10 (e.g., 1 km = 1,000 m = 100,000 cm). Science, medicine, and international trade use metric universally. The US customary system, while distinct, defines all its units in terms of metric equivalents since the Mendenhall Order of 1893.
