1 Gigawatt = 1341022.0896 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 = GW × 1341020

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