How to use Unit Converter
Convert between compatible measurement units in your browser. The selectors identify each family, including the difference between decimal megabytes and binary mebibytes.
- Enter a numeric value.
- Select source and destination units from the same measurement family.
- Convert and copy or download the result.
Good to know
- Mass and data values must be nonnegative. Signed lengths are accepted; temperatures below absolute zero are rejected.
- Data conversions measure storage size, not transfer speed. Decimal kB/MB/GB use powers of 1000; KiB/MiB/GiB use powers of 1024.
- Numbers use JavaScript floating-point arithmetic. Inputs are limited to 1,000 characters and a magnitude of 1 quadrillion. Results are rounded for display.
Common questions
Why can I not convert kilograms into meters?
Mass and length describe different physical dimensions. Only units in the same family can be converted directly.
Are MB and MiB equivalent?
No. One MB is 1,000,000 bytes, while one MiB is 1,048,576 bytes. A byte contains eight bits.
