1 Megawatt = 0.001 Gigawatt

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

GW = MW ÷ 1000

One gigawatt equals 1000 megawatts. This divides by 1000. Large power plants are often rated in GW, with individual units in MW.
