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

Quick Reference

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

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

How to Convert Watt-hour to Megawatt-hour

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

To convert Watt-hour to Megawatt-hour, divide the value by 1000000 (equivalently, multiply by 1.0000e-6). To convert Megawatt-hour back to Watt-hour, multiply by 1000000.

Example: convert 10 Wh to MWh:
10 Wh = 10 x 1.0000e-6 = 1.0000e-5 MWh

↔ Convert Megawatt-hour to Watt-hour

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.

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.
