How to Convert Metric Horsepower to BTU per Hour
- 1 PS = 2509.625906 BTU/h
- 1 BTU/h = 0.0003984657624 PS
- Example: convert 15 PS to BTU/h: 15 PS = 15 × 2509.625906 BTU/h = 37644.38859 BTU/h
Formula
BTU/h = PS × 2509.625905989
Derivation from SI units:
- 1 PS = 75 kgf·m/s = 735.49875 W (exact)
- 1 BTU/h = 1055.05585262 J ÷ 3600 s = 0.29307107 W
- 1 PS = 735.49875 W ÷ 0.2930710701722 W per BTU/h = 2509.625905989 BTU/h
Both units are defined exactly, so the factor is exact. Metric Horsepower definition: metric horsepower; BTU per Hour definition: BTU per hour.
Worked examples
- A reading of 100 PS converts to 250962.5906 BTU/h.
100 PS × 2509.625906 = 250962.5906 BTU/h - A value of 200 PS is 501925.1812 BTU/h.
200 PS × 2509.625906 = 501925.1812 BTU/h
