1 BTU/hour = 0.0004 Horsepower (mech)

Key Formulas

Kilowatt → Horsepower (mech)

hp = kW × 1.34102

Horsepower (mech) → Kilowatt

kW = hp × 0.7457

Watt → Kilowatt

kW = W × 0.001

Kilowatt → Watt

W = kW × 1000

Formula

hp = BTU/h × 0.000393

One 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.
