Hoe reken je mechanische pk om naar BTU per uur?

Vermenigvuldig de waarde in hp met 2.544,43357764: het resultaat staat in BTU/h.

BTU/h = hp × 2.544,43357764Andersom is 1 BTU/h gelijk aan 0,000393014779 hp.

Waar deze twee eenheden dienen

De mechanische paardenkracht is 745,6998715 watt en komt uit Watts eigen schatting van wat een brouwerijpaard kon, om zijn machines te verkopen in een eenheid die zijn klanten al kenden. De BTU per uur meet het vermogen van airco's in de Verenigde Staten, waar 12.000 BTU per uur één ton koeling maken, dus de warmte die nodig is om een ton ijs op een dag te smelten. De valkuil zit in één woord: de mechanische paardenkracht is 2545 BTU/h, maar de boiler horsepower van Amerikaanse ketels is 33.475, dertien keer meer, en beide worden op dezelfde catalogusbladzijde tot hp afgekort.
