Power Conversion FAQ
Everything you need to know about converting kilowatts, megawatts, and other power units.
To convert kilowatts (kW) to megawatts (MW), you divide the number of kilowatts by 1,000. The formula is: MW = kW ÷ 1,000. For example, 5,000 kW is equal to 5 MW because 5,000 ÷ 1,000 = 5.
Both kilowatts (kW) and megawatts (MW) are units of power. One kilowatt equals 1,000 watts, while one megawatt equals 1,000,000 watts. Therefore, a megawatt is 1,000 times larger than a kilowatt. kW is typically used for household appliances and small engines, while MW is used for power plants and large industrial facilities.
There are exactly 1,000 kilowatts (kW) in 1 megawatt (MW). This is because the prefix ‘kilo-‘ means one thousand and ‘mega-‘ means one million. Since 1,000,000 ÷ 1,000 = 1,000, one megawatt contains one thousand kilowatts.
A kilowatt (kW) is commonly used to measure the power output of engines, electric motors, and household appliances. For example, a typical microwave might use 1 kW of power, and residential solar panel systems are often rated in kW (e.g., a 4 kW system). It is also used by electricity suppliers to bill for power demand.
A megawatt (MW) is used to measure large-scale power generation and consumption. Power plants, wind farms, and large industrial facilities are typically rated in MW. For instance, a typical nuclear reactor produces about 1,000 MW (or 1 GW) of power, and a large wind turbine might generate 2 to 5 MW. It is also used to describe the power consumption of entire data centres or small towns.
