About the Data Storage Converter

Convert file and storage sizes. Decimal units (kB, MB, GB) use powers of 1,000, as drive makers do; binary units (KiB, MiB, GiB) use powers of 1,024, as many operating systems do.

Data Storage Converter formula

1 GB = 1,000,000,000 bytes
1 GiB = 1,073,741,824 bytes
1 byte = 8 bits

Frequently asked questions

Why does my 1 TB drive show about 931 GB?

The drive has 10¹² bytes, but your computer is counting in binary units: 10¹² ÷ 1024³ ≈ 931 GiB.
