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 = GW × 1341020One gigawatt equals 1,341,020 mechanical horsepower. This massive conversion reflects the scale difference between GW (grid power) and hp (individual motors).
