1 Megawatt = 0.001 Gigawatt
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
GW = MW ÷ 1000One gigawatt equals 1000 megawatts. This divides by 1000. Large power plants are often rated in GW, with individual units in MW.
