Unit Converter: Length, Weight & Temperature
Convert common units without leaving your workflow. Pick a measurement family, enter a value, and compare the equivalent in another unit.
How to use this tool
- Choose length, weight, or temperature.
- Select the starting unit and destination unit.
- Enter a value; the converted result updates immediately.
How the calculation works
Length and mass conversions use standard unit ratios. Temperature uses the corresponding Celsius, Fahrenheit, or Kelvin formula, so offsets are handled correctly.
A quick example
For temperature, Fahrenheit to Celsius is (°F − 32) × 5 ÷ 9. Temperature conversions are not simple ratios.
Common questions
Which unit groups are included?
The first version covers common metric and imperial length, weight, and temperature units.
Why is temperature handled differently?
Temperature scales have both different step sizes and different zero points, so the conversion includes an offset.
