Unit converter
Convert length, mass, temperature, US customary volume, speed and data storage. Data choices distinguish decimal units from binary units, preserving both conversion conventions.
Decimal kB/MB/GB use powers of 1,000; binary KiB/MiB/GiB use powers of 1,024. Volume measures use US customary units.
How to use
Choose a category and source/target units, then enter a value. Swap reverses the unit choices without changing the entered value. Results show up to 10 significant digits. Volume is not ingredient weight.
