What is a unit converter?
A unit converter changes a measurement from one unit into an equivalent value in another unit, such as kilometers to miles, kilograms to pounds or Celsius to Fahrenheit.
How does unit conversion work?
Most units are normalized to a category base unit using a standardized factor, then converted from that base into the target unit. Temperature uses formulas instead of a simple multiplier.
Metric and imperial units
The metric system is based on powers of ten, while imperial and US customary units use different historical relationships. This tool supports common units from both systems.
Data units
Decimal GB uses powers of 1000, while GiB uses powers of 1024. The distinction matters when comparing storage capacity and computer memory.
