Multipliez la valeur en hp par 1,01386966542 : le résultat est en ch.
Où ces deux unités servent
Le cheval mécanique vaut 745,6998715 watts et vient de l'estimation que Watt lui-même fit du travail d'un cheval de brasserie, pour vendre ses machines dans une unité que ses clients connaissaient. Le cheval métrique vaut exactement 735,49875 watts, soit 75 kilogrammes-force élevés d'un mètre par seconde, et reste inférieur de 1,4 pour cent au cheval mécanique. Le même moteur change de chiffre en traversant l'Atlantique : 500 PS annoncés en Allemagne deviennent 493 hp aux États-Unis, l'écart de 1,37 % venant des deux définitions, et aucune des deux fiches ne ment.
