About data conversion

How the gib to bytes converter works

Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.

Frequently asked questions about data conversion

How many bytes in a gibibyte?

Exactly 1,073,741,824 — two to the thirtieth.

How does that compare to a gigabyte?

A gigabyte is 1,000,000,000 bytes, 7.4% less.

Why does 16 GB of RAM show as 16 GB?

Because memory really is sold in binary units. It is storage that is sold decimal and reported binary.

What is 8 GiB?

8,589,934,592 bytes.

When did the prefixes arrive?

IEC standardised kibi, mebi, gibi and tebi in 1998.
