Kilowatts (kW) and milliwatts (mW) are units of power used to measure the rate at which work is done or energy is transferred. However, they differ in magnitude:

Kilowatts (kW)

Kilowatt is a unit of power in the International System of Units (SI).
1 kilowatt (kW) is equal to 1,000 watts. It represents the power required to perform 1,000 joules of work in one second.
Kilowatts are commonly used to describe the power output of electrical devices, motors, engines, and larger-scale energy generation and consumption.

Milliwatts (mW)

Milliwatt is also a unit of power in the International System of Units (SI).
1 milliwatt (mW) is equal to 0.001 watt or 1/1,000 of a watt. It represents a smaller unit of power.
Milliwatts are often used to describe low-power electronic devices, such as some sensors, small light-emitting diodes (LEDs), and low-power transmitters.

How to convert kW to mW

FAQs on kW to mW conversion

How many kWh is 1 MW?

One megawatt (MW) of power, operating for one hour, is equal to 1,000 kilowatt-hours (kWh).

Is 100 kW 1 MW?

No, 100 kW is not equal to 1 MW. One megawatt (MW) is equal to 1,000 kilowatts (kW). So, 1 MW is 10 times larger than 100 kW.

How do you convert kWh to MW?

To convert kilowatt-hours (kWh) to megawatts (MW), you need to divide the energy in kilowatt-hours by 1,000. Mathematically: 1 kWh = 0.001 MW OR kWh ÷ 1,000 = MW

What is the difference between kW to MW?

The difference between kilowatts (kW) and megawatts (MW) lies in their magnitude. One megawatt (MW) is equal to 1,000 kilowatts (kW). So, a megawatt is a larger unit of power compared to a kilowatt.

How much is 1 MW of power?

One megawatt (MW) of power is equal to 1,000 kilowatts (kW) or 1,000,000 watts (W). It represents a significant amount of electrical power, often used for larger-scale operations like industrial facilities, power plants, or data centers.

How Many Units of Electricity Are Consumed by 1 MW of Power in an Hour?

In the context of electricity billing, a unit is equivalent to one kilowatt-hour (kWh). So, 1 MW of power used for one hour will consume 1,000 kilowatt-hours (kWh), which is 1,000 units of electricity.
