How many watts are in a megawatt?

One megawatt equals exactly 1,000,000 watts (10^6 W). To convert watts to megawatts, divide the watt value by 1,000,000.

What is the formula to convert watts to megawatts?

MW = W / 1,000,000. For example, 5,000,000 W = 5 MW and 750,000 W = 0.75 MW.

Is a megawatt a unit of energy or power?

A megawatt is a unit of power — the rate at which energy is used or produced. Energy is measured in megawatt-hours (MWh), which equals one MW of power sustained for one hour.

How large is a megawatt in practical terms?

One megawatt can power roughly 400–1,000 average US homes, depending on region and season. A utility-scale solar farm typically produces 1–500 MW, and a large coal or gas power plant produces 500–3,000 MW.

When would I use megawatts instead of kilowatts?

Kilowatts (kW) are standard for household and small commercial equipment. Megawatts are used for utility-scale generation, industrial facilities, and grid-level infrastructure where kW numbers would run into the millions.
