Data storage units

Megabyte (MB): A megabyte is 1,000,000 bytes (1000 kilobytes). It is the usual unit for the size of photos, songs and documents.
Gigabyte (GB): A gigabyte is 1,000,000,000 bytes (1000 megabytes). It is the usual unit for memory cards, phone storage and mobile data plans.
Kilobyte (kB): A kilobyte is 1000 bytes. It is used for small files such as text documents and icons.
Byte (B): A byte is a group of 8 bits and the basic addressable unit of computer memory and storage. One byte can hold one of 256 values.
Terabyte (TB): A terabyte is 1,000,000,000,000 bytes (1000 gigabytes). It is the usual unit for hard drive and SSD capacities.
Bit: A bit is the smallest unit of digital information, a single binary value of 0 or 1. Eight bits make one byte.
Megabit (Mbit): A megabit is 1,000,000 bits, equal to 125,000 bytes. Internet connection speeds are quoted in megabits per second (Mbps).
Gigabit (Gbit): A gigabit is 1,000,000,000 bits, equal to 125,000,000 bytes. It is used for fast network links such as gigabit Ethernet and fiber broadband.
Kilobit (kbit): A kilobit is 1000 bits, equal to 125 bytes. It is used for audio bit rates and slow data links, in kilobits per second (kbps).
Gibibyte (GiB): A gibibyte is 1,073,741,824 bytes (1024 mebibytes). RAM sizes and the capacities reported by Windows are measured in gibibytes.
Mebibyte (MiB): A mebibyte is 1,048,576 bytes (1024 kibibytes). It is the binary counterpart of the megabyte, used by operating systems and for memory sizes.
Kibibyte (KiB): A kibibyte is 1024 bytes. It is the binary counterpart of the kilobyte and the smallest of the IEC binary multiples.
Petabyte (PB): A petabyte is 1,000,000,000,000,000 bytes (1000 terabytes). It is used for the storage of data centers and large archives.
Tebibyte (TiB): A tebibyte is 1,099,511,627,776 bytes (1024 gibibytes). It is the binary counterpart of the terabyte, about 10% larger.
Terabit (Tbit): A terabit is 1,000,000,000,000 bits, equal to 125,000,000,000 bytes. It is used for the capacity of backbone and submarine network links.
Pebibyte (PiB): A pebibyte is 1,125,899,906,842,624 bytes (1024 tebibytes). It is the binary counterpart of the petabyte, about 12.6% larger.
