Understanding Unit Conversion
Unit conversion is the process of converting a measurement from one unit to another, maintaining the same quantity. Throughout history, different civilizations developed unique measurement systems, leading to the dual system standard used worldwide today: the International System of Units (SI / Metric) and the Imperial / US Customary System.
Metric System (SI)
Based on powers of 10 (meters, grams, liters). Used universally in science and by over 95% of the global population.
Imperial & US Customary
Based on historical human measurements (inches, feet, pounds, miles). Standard in the United States and aviation.
