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 BTU par heure mesure la capacité des climatiseurs aux États-Unis, où 12 000 BTU par heure font une tonne de froid, c'est-à-dire la chaleur qu'il faut pour fondre une tonne de glace en un jour. Le piège tient dans un mot : le cheval mécanique fait 2 545 BTU/h, mais le boiler horsepower des chaudières américaines en fait 33 475, treize fois plus, et les deux s'abrègent hp sur la même page de catalogue.
