Results update as you type.
Choose a measurement and two units
Select the measurement, enter a number and choose the source and target units. Use the swap button to reverse the direction. The result updates immediately and can be copied as plain text.
Decimal and binary file sizes
KB, MB and GB use powers of 1000. KiB, MiB and GiB use powers of 1024. A 1 GB file is about 0.931 GiB; choosing the right convention helps explain differences between storage labels and operating-system displays.
Temperature is different
Length and weight use multiplication factors. Temperature also uses an offset: 0 °C equals 32 °F and 273.15 K. Values below absolute zero are rejected. Volume uses US gallons and US fluid ounces, not Imperial units.
Precision and scope
Results show up to ten significant digits. Calculations use browser floating-point arithmetic and are intended for everyday conversions. Verify critical engineering or laboratory measurements with the applicable standard. No input is sent to a server.
