Unit Converter
Convert between metric and imperial units across four measurement categories: length (metres, feet, inches, miles), weight (kilograms, pounds, ounces), temperature (Celsius, Fahrenheit, Kelvin), and volume (litres, gallons, fluid ounces).
How to use the Unit Converter
Select the measurement type (Length, Weight, Temperature, or Volume), choose your input unit and output unit from the dropdowns, then type a value. The converted result updates in real time as you type.
How unit conversions work
Each measurement type uses a base unit as a pivot. For length, the base is metres: 1 inch = 0.0254 m, 1 foot = 0.3048 m, 1 mile = 1,609.344 m. To convert from any unit to any other, the input is first converted to the base, then to the target. Temperature is handled separately with its own offset formulas: °F = (°C × 9/5) + 32, and Kelvin = °C + 273.15.
