2.2 Definitions of base units: |
The base units shall have the definitions assigned by the Minister from time to time by way of regulations, being the meaning appearing to the Minister to reproduce in English the international definition adopted by the General Conference of Weights and Measures (CGPM) and in force at the date of the making of the regulations.
3.1 The derived units are formed by combining base units with each other, by combining base units with other derived units, and by combining derived units with each other, according to the algebraic relations linking the corresponding quantities.

A prefix shall be considered to be combined with the name of the unit to which it is directly attached.
The symbol of the prefix shall be placed before the symbol of the unit without intermediate space; the whole forms the symbol of the multiple or sub-multiple of the unit. The symbol of the prefix is therefore considered to be combined with the symbol of the unit to which is directly attached, forming with it a new unit symbol which can be raised to a positive or negative power and which can be combined with other unit symbols to form the symbols for compound units.
Compound prefixes, formed by the juxtaposition of several SI prefixes, are not permitted.
The names and symbols of the decimal multiples and sub-multiples of the unit of mass are formed by the addition of the SI prefixes to the word
«gram». (symbol : g).
1 g = 0.001 kg =10-3 kg.
