How to Convert BTU per Hour to Metric Horsepower
- 1 BTU/h = 0.0003984657624 PS
- 1 PS = 2509.625906 BTU/h
- Example: convert 15 BTU/h to PS: 15 BTU/h = 15 × 0.0003984657624 PS = 0.005976986436 PS
Formula
PS = BTU/h × 0.0003984657624125
or PS = BTU/h ÷ 2509.625905989
Derivation from SI units:
- 1 BTU/h = 1055.05585262 J ÷ 3600 s = 0.29307107 W
- 1 PS = 75 kgf·m/s = 735.49875 W (exact)
- 1 BTU/h = 0.2930710701722 W ÷ 735.49875 W per PS = 0.0003984657624125 PS
Both units are defined exactly, so the factor is exact. BTU per Hour definition: BTU per hour; Metric Horsepower definition: metric horsepower.
Worked examples
- A reading of 9000 BTU/h converts to 3.586191862 PS.
9000 BTU/h × 0.0003984657624 = 3.586191862 PS - A value of 36000 BTU/h is 14.34476745 PS.
36000 BTU/h × 0.0003984657624 = 14.34476745 PS
