The International System of Units (SI) is the source document for the SI in Canada. It is essentially a practical system of units and is both coherent and decimal. This standard provides definitions for the internationally agreed base units together with their symbols; prefixes and their symbols; rules for their manipulation; and extracted historical decisions of the General Conference which relate to the SI. An appendix also provides some details regarding the practical realization of most of the base units for guidance to those who wish to generate their own primary standards.
