- Enter a value and choose the From and To units.
- Read the result, or see the full list of conversions below it.
What it converts
Length, weight and mass, volume, area, speed, temperature, time and digital storage. Common metric units and common US and UK units are included.
US and UK measures
Volume units marked US (cups, pints, quarts, gallons, fluid ounces) use US sizes. A UK pint or gallon is larger, so check which one your recipe or product uses.
Megabytes and mebibytes
Storage makers use 1 MB = 1,000,000 bytes, while many operating systems count in 1,024s, written MiB. Both are listed so you can choose the one you mean.
Accuracy
Conversions use exact defined factors, and results are shown to about ten significant digits. Very large or very small numbers appear in scientific notation.
Questions
Is my input sent anywhere?
No. The calculation runs in your browser.
How do I convert Fahrenheit to Celsius?
Choose Temperature, set From to Fahrenheit and To to Celsius, and enter the value.
Why does my hard drive show less than the box says?
The box counts in 1,000s (GB) and your computer may count in 1,024s (GiB). Compare the two units in the list to see the difference.
