base unit
unit of measurement that is adopted by convention for a base quantity
NOTE 1 – In each coherent system of units, there is only one base unit for each base quantity. In the SI for example, the metre is the base unit of length. The centimetre and the kilometre are also units of length, but they are not base units in the SI. However, in the CGS systems, the centimetre is the base unit of length.
NOTE 2 – A base unit may also serve for a derived quantity of the same dimension. For example, rainfall, when defined as volume per area (areic volume), has the metre as a coherent derived unit in the SI. The ampere, base unit of electric current, is also the coherent derived unit of scalar magnetic potential.
NOTE 3 – For the quantity “number of entities”, the number one, symbol 1, can be regarded as a base unit in any system of units.

unité de base, f
unité de mesure adoptée par convention pour une grandeur de base
NOTE 1 – Dans chaque système cohérent d'unités, il y a une seule unité de base pour chaque grandeur de base. Dans le SI par exemple, le mètre est l'unité de base de longueur. Le centimètre et le kilomètre sont aussi des unités de longueur, mais ils ne sont pas des unités de base dans le SI. Cependant, dans les systèmes CGS, le centimètre est l'unité de base de longueur.
NOTE 2 – Une unité de base peut aussi servir pour une grandeur dérivée de même dimension. Par exemple, la hauteur de pluie, définie comme un volume surfacique (volume par aire) a le mètre comme unité dérivée cohérente dans le SI. L’ampère, unité de base de courant électrique, est aussi l’unité dérivée cohérente de potentiel magnétique scalaire.
NOTE 3 – Pour la grandeur « nombre d'entités », on peut considérer le nombre un, de symbole 1, comme une unité de base dans tout système d'unités.
