Examples
- One ton of refrigeration: 12,000 BTU/h ÷ 2,509.62591 = 4.78158915 PS
- 5,000 BTU/h ÷ 2,509.62591 = 1.99232881 PS
Good to know
This uses the International Table BTU, 1055.05585262 J. Air conditioner and heater ratings quoted simply in "BTU" mean BTU per hour.
This is metric horsepower (PS, CV), 735.49875 W. It is about 1.4% smaller than mechanical horsepower (hp, about 745.7 W), so a car rated at 150 PS has about 148 hp.
