Universal Unit Converter

01 How it Works

Unit conversion relies on conversion factors. Each unit has a defined ratio relative to a standard base unit (like meters or kilograms).

Result = SourceValue × (SourceFactor / TargetFactor)

For example: 1 inch = 0.0254 meters. To convert inches to centimeters, we use this factor relative to the base unit (meter). Temperature conversions are unique because they involve an offset (e.g., 0°C = 32°F), requiring a linear formula rather than a simple multiplication.

02 Common Scenarios
