Convert Bits and Bytes, KB, MB, GB and TB

Bytes KiB MiB GiB TiB  

Computer storage disks and RAM are manufactured in binary units (power of 2) Bytes, KiB, MiB, GiB
The binary prefix convention allows common numbers such as 2048 bytes to display as round numbers, so 2 KiB

Power of 10 numbers are also calculated above (KB, MB, GB…) these are used by Apple and some hard drive manufacturers.

Many documents still incorrectly use the old-style : KB,MB,GB… prefixes to refer to a power of 2 value.
The 'B' character for Bytes is case sensitive and easily confused with 'b' for bits: Kb,Mb,Gb…
  1 Byte = 8 bits

Bytes are used to measure disc/file sizes.
bits are used to measure network or download speeds.

Convert Binary to Decimal to Hex

Typical throughputs:

Hard disk = 30 MiB per second. (x8 = 240 Mb/Sec)
Gigabit Ethernet = 125 MiB per second. (x8 = 1,000 Mb/Sec)
Solid state disc = 250 MiB per second. (x8 = 2,000 Mb/Sec)
Fibre Channel = 2,550 MiB per second. (x8 = 20,400 Mb/Sec)
