производная единица системы единиц физических величин
производная единица
Единица производной физической величины системы единиц, образованная в соответствии с уравнением, связывающим ее с основными единицами или с основными и уже определенными производными.
Примеры
1. 1 м/с - единица скорости, образованная из основных единиц СИ - метра и секунды.
2. 1 Н - единица силы, образованная из основных единиц СИ - килограмма, метра, и секунды.

derived unit
unit of measurement for a derived quantity
NOTE 1 – Some derived units in the International System of Units (SI) have special names, e.g. hertz for frequency and joule for energy, but others have compound names, e.g. metre per second for speed. Compounds including units with special names are also used, e.g. volt per metre for the electric field strength, and newton metre for torque. See in particular ISO 31 and ISO/IEC 80000.
NOTE 2 – Derived units can also be expressed by using multiples and submultiples. For example, the metre per second, symbol m/s, and the centimetre per second, symbol cm/s, are derived units of speed in the SI. The kilometre per hour, symbol km/h, is a unit of speed outside the SI but accepted for use with the SI, because the unit hour is accepted for use with the SI. The knot, equal to one nautical mile per hour, is a unit of speed outside the SI, that is used by special interest groups.

unité dérivée, f
unité de mesure d'une grandeur dérivée
NOTE 1 – Certaines unités dérivées dans le SI ont des noms spéciaux, par exemple le hertz pour la fréquence et le joule pour l'énergie, tandis que d'autres ont des noms composés, par exemple le mètre par seconde pour la vitesse. Les unités ayant des noms spéciaux sont aussi utilisées dans des noms composés, par exemple le volt par mètre pour le champ électrique et le newton mètre pour le moment de torsion. Voir en particulier l'ISO 31 et l'ISO/CEI 80000.
NOTE 2 – On peut aussi exprimer les unités dérivées en utilisant des multiples et des sous-multiples. Par exemple, le mètre par seconde, symbole m/s, et le centimètre par seconde, symbole cm/s, sont des unités dérivées de vitesse dans le SI. Le kilomètre par heure, symbole km/h, est une unité de vitesse en dehors du SI mais en usage avec le SI, parce que l'heure est une unité en usage avec le SI. Le nœud, égal à un mille marin par heure, est une unité de vitesse en dehors du SI, qui répond aux besoins spécifiques de certains groupes d’utilisateurs.
