Computer files are binary, measured as a power of 2 so 1 KiB = 1024 Bytes. This is unlike Base 10 numbers where for example 1 Megapixel = 1,000,000 pixels.
Many documents still refer to byte measues with the old-style prefixes: KB,MB,GB…
These are case sensitive and easily confused with bits: Kb,Mb,Gb…
1 Byte = 8 Bits.
1 KB ≠ 1 Kb
bits are used to measure network or download speeds,
Bytes are used to measure file sizes.
10BASE-T = 1.25 MiB per second. (10 Mb/Sec)
Hard disc = 30 MiB per second. (240 Mb/Sec)
Gigabit Ethernet = 125 MiB per second. (1,000 Mb/Sec)
Solid state disc = 250 MiB per second. (2,000 Mb/Sec)
Fibre Channel = 2550 MiB per second. (20,400 Mb/Sec)
“Failure of the Orbiter occurred because the flight system software was written using metric units, while the ground crew were entering course correction and thruster data using Imperial measures” ~ NASA Mars Climate Orbiter
