Megawatts to Watts formula
To convert megawatts to watts, multiply by 1000000.
W = MW × 1000000
Why this factor: the megawatt and the watt are both defined against the watt, so dividing one definition by the other gives 1000000 directly. Both definitions are set out in full below.
To go the other way, divide by 1000000 — or use the Watts to Megawatts converter, which is the same calculation reversed.
Worked example
Given 75 MW, multiplying by 1000000 yields 75000000 W.
75 MW × 1000000 = 75000000 W
The converter above does this for any value you type, in either direction.
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.
What is a watt?
The watt is the SI unit of power — the rate of one joule of energy per second.
Definition: Defined as 1 J/s. Named after James Watt.
Where it is used: Appliance and light-bulb ratings, audio output, and all scientific power calculations.
Megawatts vs Watts
The megawatt is a metric unit while the watt is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
Frequently asked questions
