Kilowatts to Megawatts formula
The factor from kilowatts to megawatts is 0.001.
MW = kW × 0.001
Put another way, one kilowatt is exactly 1/1,000 of a megawatt.
Why this factor: the kilowatt and the megawatt are both defined against the watt, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Megawatts to Kilowatts converter, which is the same calculation reversed.
Worked example
Take 75 kW and multiply by the factor 0.001: the result is 0.075 MW.
75 kW × 0.001 = 0.075 MW
The converter above does this for any value you type, in either direction.
What is a kilowatt?
A kilowatt is 1,000 watts, the practical unit for substantial electrical loads.
Definition: Exactly 1,000 watts.
Where it is used: Electric motor and vehicle output, heating systems, EV charger ratings, and solar array capacity.
What is a megawatt?
A megawatt is one million watts, the unit of power-station and grid-scale capacity.
Definition: Exactly 1×10⁶ watts.
Where it is used: Power plant and wind farm output, data-centre capacity, and grid demand.
Kilowatts vs Megawatts
The kilowatt and the megawatt belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
