General Conversion Calculator
Converts between the supported pairs: kilometres/miles, kilograms/pounds and Celsius/Fahrenheit.
How it works
Unit conversions
Formula and assumptions
Conversion factors are fixed approximations for distance and mass. Temperature conversion uses °F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9.
Example
Use the sample values, calculate, and change one input at a time.
