How does the data storage converter work?

Storage makers use decimal units (1 GB = 1,000,000,000 bytes) while Windows reports in binary units (1 GiB = 1,073,741,824 bytes) but labels them GB. That is why a "500 GB" drive appears as about 465 GB. Eight bits make one byte.

Frequently asked questions

Why does my 500 GB drive show 465 GB?

The maker counts 1 GB as 10⁹ bytes; Windows divides by 2³⁰ and calls it GB. 500 × 10⁹ ÷ 2³⁰ ≈ 465.7.

How many MB in a GB?

1,000 MB in a decimal GB, or 1,024 MiB in a GiB.

How many bits in a byte?

8.
