About this tool
Conversion Calculator
Convert common length, mass, temperature, area, volume, speed, time, energy and data units.
Learn how to convert common measurement units by choosing a measurement family, source unit and destination unit.
Choose a measurement family
Select length, mass, temperature, area, volume, speed, time, energy or data storage so the calculator only offers compatible units.
Convert within a family
The calculator uses standard unit relationships for each family. Temperature requires a formula rather than a simple multiplication factor.
Check the system
Some units have regional variants. For example, a US gallon is not the same as an imperial gallon. Always read the unit label before using the result.
Why precision matters
The displayed result is rounded for readability. Keep additional precision when the conversion feeds into engineering, science, finance or other calculations.
Examples
A value in meters can be converted to feet using the international foot definition. A value in Celsius is converted to Fahrenheit using the temperature relationship rather than a scale ratio.
