1 BTU/hour = 0.0004 Horsepower (mech)
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
hp = BTU/h × 0.000393One BTU per hour equals 0.000393 mechanical horsepower. Since 1 hp = 2544.43 BTU/h, dividing gives 1/2544.43 = 0.000393. Used when comparing HVAC capacity to mechanical power.
