Hoe reken je watt om naar BTU per uur?
Vermenigvuldig de waarde in W met 3,41214163313: het resultaat staat in BTU/h.
BTU/h = W × 3,41214163313Andersom is 1 BTU/h gelijk aan 0,293071070172 W.
Waar deze twee eenheden dienen
De watt is één joule per seconde en draagt sinds 1889 de naam van James Watt, wiens machines juist waren wat een maat van vermogen nodig maakte. 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. Een menselijk lichaam in rust geeft ongeveer 100 watt af, dus 340 BTU/h, en dat is de belasting die een ingenieur per aanwezige optelt voordat hij een airco bemeet: twintig mensen in een zaal zijn twee kilowatt warmte waard.
