Data Storage Converter
Convert data size among bits, bytes, decimal KB/MB/GB/TB, and binary KiB/MiB/GiB.
How to use
- Enter the data size and deliberately choose bit/byte, decimal KB/MB/GB/TB, or binary KiB/MiB/GiB as needed.
Capabilities and scope
Distinguish 1000-based decimal prefixes from 1024-based binary prefixes so storage-capacity labels can be compared correctly.
How it works
Byte is the reference: bit=0.125 B, KB=1000 B, KiB=1024 B, MB=10⁶ B, MiB=2²⁰ B, GB=10⁹ B, GiB=2³⁰ B, and TB=10¹² B.
Example
1 GiB is 1,073,741,824 B, or about 1.073741824 GB.
Useful for
- Compare storage labels in GB and GiB
- Convert bits and bytes
- Check decimal-versus-binary file-size prefixes
Before you use it
- Compression, filesystem overhead, and vendor/OS display policies are outside the conversion.

Frequently asked questions
Why are GB and GiB different?
GB is 1,000,000,000 bytes, while GiB is 2³⁰ = 1,073,741,824 bytes.
