About this tool
This converter covers eight categories: length, weight, area, volume, temperature, data storage, time and speed. Enter a value once and the table shows the same quantity in every supported unit.
Conversions use exact definitions where they exist, including the international inch, pound and nautical mile. Temperature uses the Celsius, Fahrenheit and Kelvin scales with correct offsets rather than simple ratios.
