MW to kW Calculator
Convert megawatts (MW) to kilowatts (kW) using this simple calculator. Ideal for electrical engineers, energy planners, and anyone working with large-scale power systems.
Understanding the Conversion from MW to kW
Megawatts (MW) and kilowatts (kW) are both units of electrical power. Understanding how to convert between them is essential for anyone working with energy production, transmission, or large-scale systems such as power plants, data centers, or electric grids.
What is a Megawatt (MW)?
A megawatt is a unit of power equal to one million watts. It is used to express the output or capacity of large systems like:
- Utility-scale power plants
- Commercial wind and solar farms
- Large data centers
- Heavy industrial machinery
What is a Kilowatt (kW)?
A kilowatt is equal to 1,000 watts. It is a more common unit in residential and small commercial contexts, such as:
- Household appliance ratings
- Small backup generators
- Electric vehicle (EV) chargers
Conversion Formula
kW = MW × 1,000
Since 1 megawatt equals 1,000 kilowatts, the conversion is simply multiplying the MW value by 1,000.
Example Calculations
- 1 MW = 1,000 kW
- 2.5 MW = 2,500 kW
- 0.75 MW = 750 kW
- 10 MW = 10,000 kW
Why Is This Conversion Useful?
Converting megawatts to kilowatts helps when:
- Designing energy systems that need both large and small components to work together
- Comparing generator sizes across different scales
- Scaling data center loads or renewable energy generation
- Estimating household or neighborhood energy needs from utility-level output
Power System Examples
| System | MW | kW Equivalent |
|---|---|---|
| Large Wind Turbine | 3.2 MW | 3,200 kW |
| Small Solar Farm | 1.5 MW | 1,500 kW |
| Combined Backup Generators | 0.8 MW | 800 kW |
| Medium Data Center | 5 MW | 5,000 kW |

- MW to kWh: Multiply by number of hours (e.g., 1 MW × 3 h = 3,000 kWh)
Frequently Asked Questions
Is 1 MW bigger than 1 kW?
Yes. 1 MW = 1,000 kW. Megawatts are used for much larger energy systems.
Can generators be rated in megawatts?
Yes, especially for commercial or utility-scale generators. Residential generators are usually rated in kW.
How much power does a small town use?
It depends on the population, but many small towns require between 5 and 20 MW during peak usage, which equals 5,000 to 20,000 kW.
How do I go from kW to MW?
Simply divide by 1,000. For example, 2,000 kW = 2 MW.
