HOW IT WORKS

Choose a category and the source and target units.

Enter a value and read the converted result.

Swap units to check the reverse conversion.

Worked examples

Length uses result = input × source factor ÷ target factor. Temperature also needs an offset: °C = (°F − 32) × 5 ÷ 9. One MiB is 1,048,576 bytes; one MB is 1,000,000 bytes.

Example	Input / settings	Expected result
Inches to centimeters	`1 in → cm`	`2.54 cm`
Fahrenheit to Celsius	`32 °F → °C`	`0 °C`
Binary to decimal data units	`1 MiB → MB`	`1.048576 MB`

Rules and limits

Temperature uses offsets; other units use fixed conversion factors. US and UK gallons differ. Data units distinguish decimal kB from binary KiB. Results use up to 13 significant digits.
