kW to MW
Professional-grade kW to MW calculator with real-time results. Built for electrical engineers, energy professionals, and students.
Convert Kilowatts to Megawatts
To convert kilowatts (kW) to megawatts (MW), divide the kilowatt value by 1,000. One megawatt equals 1,000 kilowatts in the International System of Units (SI), the global standard maintained by the National Institute of Standards and Technology (NIST). This kW to MW conversion applies across all areas of electricity and power measurement — from residential solar panels rated at 5–15 kW to utility-scale wind turbines producing 2–8 MW.
Power unit conversions between kilowatt and megawatt are used daily by electrical engineering professionals, energy analysts at organizations like the U.S. Energy Information Administration (EIA) and International Energy Agency (IEA), and equipment manufacturers including General Electric, Siemens, ABB, and Schneider Electric. This kW to MW converter provides accurate, real-time results for any power conversion need.
Understanding Power Measurements
Kilowatt (kW) and megawatt (MW) are both units of power in the International System of Units (SI), measuring the rate of energy transfer in electricity systems.
What is a Kilowatt (kW)?
A kilowatt (kW) equals 1,000 watts (W). The kilowatt measures the rate of electrical energy transfer and is the standard unit for residential and commercial power equipment. Home appliances, electric vehicle (EV) chargers, residential solar panel systems, and commercial motors all use kilowatt ratings.
- 🏠 Home air conditioner: 3–5 kW
- 🚗 EV level 2 charger: 7–22 kW
- ☀️ Residential rooftop solar: 5–15 kW
- ⚙️ Commercial standby generator: 20–50 kW
- 🏭 Commercial HVAC unit: 50–150 kW
What is a Megawatt (MW)?
A megawatt (MW) equals 1,000,000 watts (W) or 1,000 kilowatts (kW). The megawatt is the standard unit for large-scale power generation and grid-level electricity. Utility wind turbines, power plant capacities, hyperscale data centers, and regional power grids all use megawatt measurements.
- 🌊 Onshore wind turbine: 2–5 MW
- 🌊 Offshore wind turbine: 8–15 MW
- 🖥️ Hyperscale data center: 20–100 MW
- ⚡ Gas turbine power plant: 200–500 MW
- ☢️ Nuclear power reactor: 900–1,600 MW
kW to MW Conversion Formula
To convert kW to MW, divide the kilowatt value by 1,000. The conversion factor is 0.001 because one kilowatt equals one-thousandth of a megawatt.
The kW to MW Formula
Since 1 megawatt (MW) = 1,000 kilowatts (kW), the kW to MW conversion factor is 0.001. Multiply any kW value by 0.001, or divide by 1,000, to get the exact MW value.

MW to kW (Reverse Conversion)
To convert MW back to kW, multiply the megawatt value by 1,000. For example, 2.5 MW × 1,000 = 2,500 kW.

Frequently Asked Questions
How many kilowatts are in one megawatt?
One megawatt (MW) contains exactly 1,000 kilowatts (kW). The prefix "mega" represents 10⁶ (1,000,000) and "kilo" represents 10³ (1,000) in the International System of Units (SI). Dividing 1,000,000 watts by 1,000 gives 1,000 kW per MW.
Is a megawatt larger than a kilowatt?
Yes, a megawatt (MW) is 1,000 times larger than a kilowatt (kW). One MW equals 1,000 kW, or 1,000,000 watts (W). Kilowatts measure smaller-scale power like household appliances (1–5 kW) and EV chargers (7–22 kW). Megawatts measure large-scale power like wind turbines (2–8 MW) and power plant capacity (200–1,400 MW).
How much is 500 kW in MW?
500 kW equals 0.5 MW. Calculation: 500 ÷ 1,000 = 0.5 MW. A 500 kW power rating is typical for a mid-size commercial diesel generator from manufacturers like Caterpillar or Cummins, or a small commercial solar installation.
What is the difference between kW and MW?
The difference between kilowatts (kW) and megawatts (MW) is scale. One kW equals 1,000 watts. One MW equals 1,000,000 watts, or 1,000 kW. Kilowatts are used for residential and commercial equipment — home appliances, EV chargers, generators. Megawatts are used for grid-scale power — wind turbines, gas turbines, nuclear reactors, and large data centers.
Where are megawatts commonly used?
Megawatts (MW) are commonly used in 5 main areas: power plant capacity ratings, wind turbine output, utility-scale solar farms, hyperscale data center power demand, and national electricity grid management.
Can MW be converted back to kW?
Yes, MW can be converted back to kW by multiplying the megawatt value by 1,000. The reverse formula is: kW = MW × 1,000. For example, 2.5 MW × 1,000 = 2,500 kW.
What is the relationship between watts, kilowatts, and megawatts?
Watts (W), kilowatts (kW), and megawatts (MW) are all units of power in the International System of Units (SI), related by factors of 1,000. 1 kW = 1,000 W, and 1 MW = 1,000 kW = 1,000,000 W. Each step up multiplies by 1,000.
What does kW stand for in power measurements?
kW stands for kilowatt. The lowercase "k" represents the metric prefix "kilo" (meaning 1,000) and the uppercase "W" represents the watt, the SI unit of power named after Scottish inventor James Watt. One kilowatt equals 1,000 watts of power.
