How to Convert Watts to Megawatts

To convert a measurement in watts to a measurement in megawatts, divide the power by the following conversion ratio: 1,000,000 watts/megawatt.

Since one megawatt is equal to 1,000,000 watts, you can use this simple formula to convert:

megawatts = watts ÷ 1,000,000

The power in megawatts is equal to the power in watts divided by 1,000,000.

For example, here's how to convert 5,000,000 watts to megawatts using the formula above.
megawatts = (5,000,000 W ÷ 1,000,000) = 5 MW

Watts and megawatts are both units used to measure power. Keep reading to learn more about each unit of measure.

What Is a Watt?

One watt is the power equal to the rate of energy of one joule per second in an electrical circuit.[1] One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.

The watt is the SI derived unit for power in the metric system. Watts can be abbreviated as W; for example, 1 watt can be written as 1 W.

Watt's Law states the relationship between power, current, and voltage. Using Watt's Law, it's possible to express the power in watts as an expression using current and voltage.

PW = IA × VV

The power in watts is equal to the current in amperes times the potential difference in volts.

Combining this with Ohm's Law, it's also possible to express the power in watts using resistance in addition to volts and amps.

What Is a Megawatt?

One megawatt is the power equal to 1,000,000 watts, or the energy consumption at a rate of 1,000,000 joules per second.

The megawatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "mega" is the prefix for millions, or 106. Megawatts can be abbreviated as MW; for example, 1 megawatt can be written as 1 MW.
