About Converting Megawatts to Kilowatts

Megawatt and Kilowatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Megawatt is 1000000 watt units, and kilowatt is 1000 watt units.

Formula

kilowatts = megawatts × 1000

This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 kilowatt equals 1000 base units, so dividing one by the other gives the direct megawatt-to-kilowatt factor of 1000.

Simple example

1 MW × 1000 = 1,000 kW

1 megawatt = 1,000 kilowatts.

Real-world example

100 MW × 1000 = 100,000 kW

100 megawatts = 100,000 kilowatts.

Reverse conversion: Kilowatt to Megawatt

1 kW × 0.001 = 0.001 MW

1 kilowatt = 0.001 megawatts.

megawatts = kilowatts × 0.001

Understanding the Megawatt (MW)

Megawatt is 1000000 watt units.

Understanding the Kilowatt

Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.

Where it's used: Standard power unit worldwide for larger appliances, vehicles, and electrical systems

Uses of the Kilowatt today

  • Electric vehicle motor power ratings (alongside horsepower)
  • Household electrical system and generator capacity
  • Industrial motor and equipment power ratings

History of the Kilowatt

The kilowatt follows directly from the watt via the standard SI 'kilo-' prefix, becoming especially prominent with the growth of electrical power generation and distribution in the late 19th and 20th centuries.

Historical origin. Kilowatt was not the invention of a single named person; it developed through the process described above.

Frequently asked questions

How many kilowatts are in 1 megawatt?

1 megawatt equals 1,000 kilowatts, using the exact defined conversion factor rather than an estimate.

How do I convert megawatt to kilowatt?

Multiply the megawatt value by 1000. The converter above does this instantly to whatever precision you set.

How do I convert kilowatt back to megawatt?

Use the reverse factor: 1 kilowatt equals 0.001 megawatts. You can also use the swap control in the converter above to flip the direction instantly.

What is a megawatt?

Megawatt (MW) is a unit of power.

What is a kilowatt?

Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.

Is the megawatt to kilowatt conversion exact?

Yes. Both megawatt and kilowatt are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
