Contents Options

Notes

EXAMPLE 1 The kilometre is a decimal multiple of the metre.

EXAMPLE 2 The hour is a non-decimal multiple of the second.

NOTE 1 SI prefixes for decimal multiples of SI base units and SI derived units are given in Note 5 of 1.16.

NOTE 2 SI prefixes refer strictly to powers of 10, and should not be used for powers of 2. For example, 1 kilobit should not be used to represent 1 024 bits (210 bits), which is 1 kibibit.
