coherent system of units
system of units, based on a given system of quantities, in which the unit of measurement for each derived quantity is a coherent derived unit
NOTE 1 – A system of units can be coherent only with respect to a system of quantities and the adopted base units.
NOTE 2 – For a coherent system of units, numerical value equations have the same form, including numerical factors, as the corresponding quantity equations.
NOTE 3 – An example of coherent system of units is the set of coherent SI units with the relations between them.

système cohérent d'unités, m
système d'unités, fondé sur un système de grandeurs donné, dans lequel l'unité de mesure de chaque grandeur dérivée est une unité dérivée cohérente
NOTE 1 – Un système d'unités ne peut être cohérent que par rapport à un système de grandeurs et aux unités de base adoptées.
NOTE 2 – Pour un système cohérent d'unités, les équations aux valeurs numériques ont la même forme, y compris les facteurs numériques, que les équations aux grandeurs correspondantes.
NOTE 3 – Un exemple de système cohérent d’unités est l’ensemble des unités SI cohérentes muni des relations entre elles.
