1 BTU/hour = 0.0004 Horsepower (metric)

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

PS = BTU/h × 0.00039897

One BTU per hour equals 0.000399 metric horsepower. Since 1 PS = 2509.96 BTU/h, dividing gives 1/2509.96 = 0.000399. Used when comparing HVAC to European power specs.
