Digital storage is measured in units such as bit, B, KB, MB, GB, TB, KiB, MiB, GiB, TiB. Pick a source and target unit above, enter a value, and the result appears instantly — free and entirely in your browser. Below you'll find the most common individual conversions as dedicated pages.
Which digital storage units are there?
- Bit (bit) — A bit is the smallest unit of digital information, a single 0 or 1. Eight bits make one byte. Network speeds and data rates are usually given in bits.
- Byte (B) — A byte is eight bits and the basic unit of file size. One character of text is roughly one byte; larger files are measured in kilobytes, megabytes and gigabytes.
- Kilobyte (1000) (KB) — A kilobyte (KB) is 1,000 bytes in the decimal system used by storage makers. Some software instead means 1,024 bytes — that is a kibibyte (KiB).
- Megabyte (1000) (MB) — A megabyte (MB) is 1,000,000 bytes (decimal). A few minutes of MP3 audio or one high-quality photo is a few megabytes.
- Gigabyte (1000) (GB) — A gigabyte (GB) is 1,000 megabytes (decimal). It is the everyday unit for phone storage, mobile data plans and downloads.
- Terabyte (1000) (TB) — A terabyte (TB) is 1,000 gigabytes (decimal). Modern hard drives and large backups are measured in terabytes.
- Kibibyte (1024) (KiB) — A kibibyte (KiB) is exactly 1,024 bytes — the binary unit used by operating systems, where many tools still label it 'KB'.
- Mebibyte (1024) (MiB) — A mebibyte (MiB) is exactly 1,048,576 bytes (1,024 KiB), the binary counterpart of the megabyte used by operating systems and RAM.
- Gibibyte (1024) (GiB) — A gibibyte (GiB) is exactly 1,073,741,824 bytes (1,024 MiB). It is why a '1 TB' drive shows as about 931 GiB in your operating system.
- Tebibyte (1024) (TiB) — A tebibyte (TiB) is 1,024 gibibytes, the binary counterpart of the terabyte used by operating systems and storage software.
Key facts about digital storage
Decimal units (KB, MB, GB) are used by drive makers and networks; binary units (KiB, MiB, GiB) by operating systems and RAM. The roughly 7% gap per step is why drives look 'smaller' than advertised.
Storage makers use decimal units: 1 GB = 1,000 MB = 1,000,000,000 bytes. Operating systems often show binary units, where 1 GiB = 1,024 MiB — which is why a '1 TB' drive appears as about 931 GiB (IEC 80000-13).
