How to convert data storage units

Data is based on the byte (one byte is 8 bits). There are two families of units: decimal units (kB, MB, GB, TB) step by 1,000, while binary units (KiB, MiB, GiB, TiB) step by 1,024. Mixing the two is why a "500 GB" drive shows as about 466 GiB in your operating system.

Worked example

One GB is 1,000,000,000 bytes, while one GiB is 1,073,741,824 bytes, so 1 GiB ≈ 1.074 GB. A 500 GB drive is 500 ÷ 1.073741824 = 465.66 GiB.

What is the difference between GB and GiB?

One byte equals 8 bits. Decimal: 1 kB = 1,000 B, 1 MB = 1,000,000 B, 1 GB = 1,000,000,000 B. Binary: 1 KiB = 1,024 B, 1 MiB = 1,048,576 B, 1 GiB = 1,073,741,824 B. So one GiB is about 7.4% larger than one GB.

When you'll use a data converter

Data conversion is useful for file and storage sizes, bandwidth, RAM, and comparing advertised versus actual disk capacity. The table above lists your value in all 10 supported units, across both decimal and binary families.
