Decimal versus binary units

There are two ways to count storage. Decimal units use powers of 1,000: 1 MB = 1,000,000 bytes and 1 GB = 1,000 MB. Drive makers and network speeds use these. Binary units use powers of 1,024: 1 MiB = 1,048,576 bytes and 1 GiB = 1,024 MiB. Memory (RAM) is sized this way, and Windows reports disk space in binary units while labelling them “GB”.

That is why a 1 TB drive shows as about 931 GB in Windows: 1,000,000,000,000 bytes ÷ 1,024³ = 931.3 GiB. No space is missing.

Bits and bytes

A byte is 8 bits. Storage is measured in bytes (capital B), while connection speeds are measured in bits per second (lower-case b).

Frequently asked questions

How many MB are in a GB?

There are 1,000 megabytes in a gigabyte (decimal). In binary units, one gibibyte (GiB) is 1,024 mebibytes (MiB).

Why does my 1 TB drive show 931 GB?

The drive holds 1,000,000,000,000 bytes. Windows divides by 1,024³ and shows 931 "GB", which are really gibibytes.

How many bytes are in a kilobyte?

A kilobyte (kB) is 1,000 bytes. A kibibyte (KiB) is 1,024 bytes.

What is the difference between a bit and a byte?

A bit is a single 0 or 1. A byte is a group of 8 bits.
