Como converter watts para BTU por hora
Multiplique o valor em W por 3,41214163313: o resultado está em BTU/h.
BTU/h = W × 3,41214163313No sentido inverso, 1 BTU/h = 0,293071070172 W.
Onde estas duas unidades se usam
O watt vale um joule por segundo e leva desde 1889 o nome de James Watt, cujas máquinas tinham tornado necessária justamente uma medida da potência. O BTU por hora mede a capacidade dos aparelhos de ar condicionado nos Estados Unidos, onde 12 000 BTU por hora fazem uma tonelada de refrigeração, ou seja o calor que funde uma tonelada de gelo num dia. Um corpo humano em repouso liberta cerca de 100 watts, ou seja 340 BTU/h, e é essa a carga que um gabinete técnico acrescenta por ocupante antes de dimensionar um climatizador: vinte pessoas numa sala valem dois quilowatts de calor.
