Kilowatts to megawatts (kW to MW) converter

What is a kilowatts to megawatts converter?

A kilowatts to megawatts converter is an online tool that helps you express a quantity of power given in kilowatts (kW) as its equivalent in megawatts (MW), and vice versa. Both units measure power, the rate at which energy is produced or consumed, and they belong to the same metric family. Because they differ only by a factor of one thousand, switching between them is a matter of moving the decimal point. The converter removes the guesswork and lets you move freely between small ratings and large-scale ones, while also offering horsepower (hp) and watts (W) for added flexibility.

How does the converter work?

Enter a value in either field and the other field updates instantly. Each field has a unit selector, so you can choose whether you are working in kilowatts, megawatts, horsepower, or watts. Internally, every value is normalized to a common base unit before being expressed in the unit you selected, which keeps results consistent regardless of the direction you convert in. Because the relationship between kilowatts and megawatts is fixed, the conversion is exact: there is no rounding error introduced by the metric prefixes themselves.

Formula for conversion

The kilo prefix means one thousand, and the mega prefix means one million. Since one megawatt equals one thousand kilowatts, the conversions are straightforward:

To convert kilowatts to megawatts: $\text{MW} = \text{kW} \div 1000$

To convert megawatts to kilowatts: $\text{kW} = \text{MW} \times 1000$

If you also need horsepower (mechanical), one kilowatt is approximately 1.34102 hp, based on one horsepower equalling 745.699872 watts: $\text{hp} = \text{kW} \times \frac{1000}{745.699872}$

Conversion table

The following table shows common kilowatt values and their megawatt equivalents:

Examples

Example 1: Kilowatts to megawatts

A solar farm has a combined inverter rating of 1000 kW. To express this in megawatts, divide by 1000:

$1000 \text{ kW} \div 1000 = 1 \text{ MW}$

Example 2: Megawatts to kilowatts

A gas turbine is rated at 1 MW. Converting to kilowatts gives:

$1 \text{ MW} \times 1000 = 1000 \text{ kW}$

Example 3: A larger megawatt rating

A wind turbine is rated at 5 MW. To find its rating in kilowatts:

$5 \text{ MW} \times 1000 = 5000 \text{ kW}$

Example 4: Kilowatts to horsepower

Suppose you want to express 1 kW of engine output in mechanical horsepower:

$1 \text{ kW} \times \frac{1000}{745.699872} \approx 1.34102 \text{ hp}$

Notes

• The conversion between kilowatts and megawatts is exact because both are metric units that differ only by the factor 1000.
• A power plant rated at 250000 kW is the same as 250 MW; large generators are almost always quoted in megawatts to keep the numbers manageable.
• Do not confuse power units (kW, MW) with energy units such as kilowatt-hours (kWh) or megawatt-hours (MWh). Power is a rate; energy is power accumulated over time.
• Horsepower comes in several definitions. This converter uses mechanical horsepower (about 745.7 W), which differs slightly from metric horsepower.

Frequently asked questions

How many kilowatts are in 1 megawatt?

There are exactly 1000 kilowatts in 1 megawatt. To convert any megawatt value to kilowatts, multiply it by 1000.

How do I convert kilowatts to megawatts?

Divide the number of kilowatts by 1000. For example, 1000 kW divided by 1000 equals 1 MW.

Is the conversion between kW and MW exact?

Yes. Both units are part of the metric system and are linked by the fixed factor of 1000, so no approximation or rounding is required.

What is the difference between a kilowatt and a megawatt?

Both measure power, but a megawatt is one thousand times larger than a kilowatt. Kilowatts are typical for household appliances and small machinery, while megawatts describe power stations, large industrial loads, and grid-scale generation.

Why is large-scale power measured in megawatts?

For big installations, kilowatt figures become very large and unwieldy. Quoting a 250000 kW plant as 250 MW is shorter, clearer, and the industry standard for utility-scale equipment.

Can I also convert to watts or horsepower?

Yes. Each field includes a unit selector that lets you choose kilowatts, megawatts, watts, or horsepower, so you can convert across all four units in either direction.
