Data-Size Units and Descriptions

Below are descriptions and historical context for each Data-Size unit available in this converter.

Bit (b)

Bit, the fundamental unit of information. Coined by Claude Shannon in 1948, short for 'binary digit'.

Nibble (nibble)

A nibble is a unit of data that consists of four bits, which is exactly half of a standard 8-bit byte.

Byte (B)

Byte, typically 8 bits. Term coined by Werner Buchholz at IBM in 1956.

Block (Block)

A data block is a unit of data, a sequence of bits or bytes transferred as a whole, used for efficient storage and retrieval. In computing, this can refer to the smallest storage unit in a database, a set of data for a report, or a security measure to prevent data transfer.

Kilobit (kb)

A unit of computer memory or data equal to 1,024 (2^10) bits.

Kilobyte (kB)

Kilobyte, 1000 bytes in decimal system. Used by storage manufacturers and in SI standard.

Kibibyte (kiB)

Kibibyte, 1024 bytes in binary system. IEC standard introduced in 1998 to avoid confusion.

Megabit (Mb)

A unit of data size equal to one 1,048,576 (2^20)) bits.

Megabyte (MB)

Megabyte, 1,000,000 bytes in decimal system. Commonly used for file sizes and storage.

Mebibyte (MiB)

Mebibyte, 1,048,576 bytes in binary system. More accurate for computer memory measurements.

Gigabit (Gb)

A unit of data size equal to 1,073,741,824 (2^30) bits.

Gigabyte (GB)

Gigabyte, 1 billion bytes in decimal system. Standard for hard drive and storage capacity.

Gibibyte (GiB)

Gibibyte, 1,073,741,824 bytes in binary system. Used in operating systems and RAM specifications.

Terabit (Tb)

A terabit is 1 trillion bits.

Terabyte (TB)

Terabyte, 1 trillion bytes in decimal system. Used for large storage devices and data centers.

Tebibyte (TiB)

Tebibyte, 1,099,511,627,776 (2^40) bytes in binary system. Precise measurement for large memory systems.
