Megawatt-hour [MWh] to Watt-hour [Wh] Converter

Quick Reference

1 Megawatt-hour (MWh) = 1000000 Watt-hour (Wh)

1 Watt-hour (Wh) = 1.0000e-6 Megawatt-hour (MWh)

How to Convert Megawatt-hour to Watt-hour

1 MWh = 1000000 Wh
1 Wh = 1.0000e-6 MWh

To convert Megawatt-hour to Watt-hour, multiply the value by 1000000. To convert Watt-hour back to Megawatt-hour, divide by 1000000.

Example: convert 10 MWh to Wh:
10 MWh = 10 x 1000000 = 10000000 Wh

↔ Convert Watt-hour to Megawatt-hour

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.

Watt-hour

Definition: A watt-hour (symbol Wh) is a unit of energy equal to one watt of power sustained for one hour. It is commonly used to measure electrical energy consumption.

History/origin: The watt-hour is derived from the watt, the SI unit of power, and the hour, a unit of time. It was developed alongside the increasing use of electricity in the late 19th and early 20th centuries.

Current use: Watt-hours are commonly used to measure the energy capacity of batteries, the energy consumption of household appliances, and the amount of electricity generated or consumed by power plants and consumers.
