1 Horsepower (mech) = 2544.4336 BTU/hour
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
BTU/h = hp × 2544.43One mechanical horsepower equals 2544.43 BTU per hour. Since 1 hp = 745.7 W and 1 W = 3.412 BTU/h, multiplying gives 2544.43. Used when comparing engine power to HVAC equipment.
