We often see mistakes in the binary units in French, for example, things such as:

  • Kbit (the abbreviation for kilo should be k not K),
  • Mbits/s (Mbit/s is correct, the plural s is not used)
  • Gbps (Gbit/s is correct, Gbps is the English version)
  • GB translated Gb (Go is correct, bits and bytes are different)

The following table should be enough in most cases:

b bit bit bit Bit values are 1 and 0
kb kilobit kbit kilobit A kilobit is 1,024 bits
