Bit Units

Standard Reference

KB / MB / GB

Decimal units are commonly used for drives, cloud storage and network transfer labels.

1 KB = 1,000 B

KiB / MiB / GiB

Binary units are commonly used by operating systems and memory capacity, using powers of 1024.

1 KiB = 1,024 B

bit and Byte

Lowercase b means bit, uppercase B means Byte. Network bandwidth is usually measured in bits.

1 B = 8 b

Byte Converter Overview

The byte converter converts between bit, Byte, KB, KiB, MB, MiB, GB, GiB, TB, TiB and related units. It is useful for file sizes, bandwidth, storage capacity and development debugging.

KB vs KiB

KB, MB and GB are decimal units based on 1000:

1 KB = 1,000 B
1 MB = 1,000 KB
1 GB = 1,000 MB

KiB, MiB and GiB are binary units based on 1024:

1 KiB = 1,024 B
1 MiB = 1,024 KiB
1 GiB = 1,024 MiB

bit vs Byte

Lowercase b means bit. Uppercase B means Byte. 1 Byte equals 8 bits. Network bandwidth usually uses bits per second, while file sizes usually use Byte, KB, MB or GB.

Common Use Cases

Convert file sizes, such as 1536 MB to GB or GiB.
Estimate download speed by converting Mb to MB.
Compare drive labels in GB with operating system values in GiB.
Debug cache, logs, object sizes and transferred payloads.

FAQ

Why does a 1 TB drive show less than 1 TB in the operating system?
Drive vendors usually use decimal TB, while the operating system may show binary TiB, so the displayed number is smaller.

Are MB/s and Mb/s the same?
No. MB/s means megabytes per second, while Mb/s means megabits per second. 1 MB/s = 8 Mb/s.
