Byte Converter — B, KiB, MiB, GiB, TiB | How to use and interpret results
Convert storage sizes with a fixed factor of 1024 between adjacent units. Distinguish the selector's familiar KB or MB labels from the binary KiB and MiB result labels.

How to use this tool
Choose a number and its source and target units. This page uses 1024 throughout; use a decimal-base converter for a capacity advertised with powers of 1000.
Results and examples
1024 MiB equals 1 GiB, while 1 MiB equals 1,048,576 bytes. Keep the binary unit with the number so it is not confused with decimal megabytes.
Worked example
1024 MiB equals 1 GiB, while 1 MiB equals 1,048,576 bytes. Keep the binary unit with the number so it is not confused with decimal megabytes.
Limitations
- Bit rates are not converted into stored byte counts.
- Compression ratios and filesystem-reserved capacity are not predicted.
