The process of changing a measurement from one unit to another while maintaining the same quantity or value. This involves multiplying by conversion factors that represent equivalent relationships between units.
From Latin 'unus' meaning 'one' and 'convertere' meaning 'to turn around' or 'transform'. The systematic approach to unit conversion developed alongside the metric system in the 18th century and became essential for international scientific collaboration.
Unit conversion is mathematics' universal translator! It's what lets NASA engineers work with European scientists, enables international recipes to work in any kitchen, and prevents billion-dollar spacecraft from crashing due to mixing up meters and feet.
