How do you convert megawatts to kilowatts?

To convert megawatts (MW) to kilowatts (kW), multiply the power in megawatts by 1,000 (kilowatts = megawatts × 1,000).

What is 2.5 megawatts in kilowatts?

2.5 megawatts (2.5 MW) is equal to 2,500 kilowatts (2,500 kW).

Which is larger, 1 megawatt (MW) or 1 kilowatt (kW)?

One megawatt (MW) is larger than one kilowatt (kW). Specifically, 1 MW contains 1,000 kW, whereas 1 kW is 0.001 MW.

How do I convert back from kilowatts (kW) to megawatts (MW)?

To reverse the calculation from kW to MW, multiply your kilowatt value by the inverse factor 0.001 (or divide by 1,000). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round MW to kW results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 2.5 MW ≈ 2,500.00 kW). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Megawatts to Kilowatts

To convert megawatts to kilowatts, multiply the power by the following conversion ratio: 1,000 kilowatts/megawatt.

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

kilowatts = megawatts × 1,000

The power in kilowatts is equal to the power in megawatts multiplied by 1,000.

For example, here's how to convert 2.5 megawatts to kilowatts using the formula above.

kilowatts = (2.5 MW × 1,000) = 2,500 kW

How Many Kilowatts Are in a Megawatt?

There are 1,000 kilowatts in a megawatt, which is why we use this value in the formula above.

1 MW = 1,000 kW|1 kW = 0.001 MW

Our megawatt to kilowatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Megawatts and kilowatts are both units used to measure power. Keep reading to learn more about each unit.

What Is a Megawatt?

A megawatt is a unit of power equal to 1,000,000 watts (W), the base unit for power. Equal to 1,000,000 Watts (1,000 kW). [1]

The megawatt is classified as a metric and SI-compatible unit of power. Megawatts can be abbreviated as MW; for example, 1 megawatt can be written as 1 MW.

In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megawatt (MW) a convenient decimal multiple of the watt (W).

In practice, megawatts (MW) are widely used across large-scale industrial, bulk, and macro-level power specifications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Kilowatt?

A kilowatt is a unit of power equal to 1,000 watts (W), the base unit for power. Equal to 1,000 Watts (1 kJ/s). [2]

The kilowatt is classified as a metric and SI-compatible unit of power. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilowatt (kW) a convenient decimal multiple of the watt (W).

In practice, kilowatts (kW) are widely used across large-scale industrial, bulk, and macro-level power specifications within SI metric workflows, engineering documentation, and technical data sheets.

Learn more about kilowatts in our Power Converter.

When converting power between megawatts (MW) and kilowatts (kW), keep full floating-point precision (1 MW = 1,000 kW; 1 kW = 0.001 MW) during intermediate calculations and round only the final kilowatt figure to match your instrument tolerance.
