What Is Unit Conversion?
Unit conversion is the process of converting a measure of physical quantity from one unit to another, for instance, converting your height from inches to centimeters.
The process for converting between units is to multiply or divide by a conversion factor to convert from one unit of measure to the target unit.
Sounds complicated? It may seem complex, but in practice, it's simpler than it sounds once you know the conversion factor between units.
