Data Size
Convert a data size into every common unit at once, showing both the 1024-based binary units (KiB, MiB, GiB) and the 1000-based decimal units (kB, MB, GB).
Frequently asked questions
- Why are there two sets of units?
- Disk makers use decimal units (1 GB = 1000 MB) while operating systems often report binary units (1 GiB = 1024 MiB). The table shows both.
- Which one is a megabyte?
- MB is 1,000,000 bytes; MiB is 1,048,576 bytes.
