Quick reference
1 KB = 1,000 B (SI)
1 KiB = 1,024 B (IEC)
1 MB = 1,000 KB
1 MiB = 1,024 KiB
1 GB = 1,000 MB
1 GiB = 1,024 MiB

How it works
- Enter a value in any unit field (e.g. type 1 in the GB field).
- All other units update instantly in both SI and IEC columns.
- Switch the input unit by typing into a different field.
- Click "Clear all" to reset the form.
Use cases
- Convert file sizes shown by an OS (IEC, base-1024) vs. a hard drive spec (SI, base-1000).
- Calculate how many files fit on a storage device.
- Understand the difference between GB and GiB when provisioning cloud storage.
- Convert network transfer sizes for bandwidth planning.
