How to Convert Kilowatt-hour to Megawatt-hour

1 kWh = 0.001 MWh
1 MWh = 1000 kWh

To convert Kilowatt-hour to Megawatt-hour, divide the value by 1000 (equivalently, multiply by 0.001). To convert Megawatt-hour back to Kilowatt-hour, multiply by 1000.

Example: convert 10 kWh to MWh:
10 kWh = 10 x 0.001 = 0.01 MWh

↔ Convert Megawatt-hour to Kilowatt-hour

Kilowatt-hour

Definition: A kilowatt-hour (symbol kWh) is a unit of energy equal to one kilowatt (1,000 watts) of power sustained for one hour. It is a standard unit for measuring electrical energy consumption.

History/origin: The kilowatt-hour became widely adopted with the expansion of electrical grids and the need for a practical unit to measure household and industrial energy usage.

Current use: Kilowatt-hours are the standard unit used by utility companies to bill consumers for electricity usage. It's also used to specify the energy output of power plants and the energy consumption of large appliances.

Megawatt-hour

Definition: A megawatt-hour (symbol MWh) is a unit of energy equal to one megawatt (1,000,000 watts) of power sustained for one hour. It represents a large amount of energy.

History/origin: The megawatt-hour is a derivative of the watt-hour, using the SI prefix 'mega-' to denote a factor of one million. It was developed to represent energy production and consumption on a larger scale.

Current use: Megawatt-hours are used to measure the energy output of large power plants, the energy consumption of large industrial facilities, and the trading of electricity on wholesale markets.
