Milliwatt-hour [mWh] to Megawatt-hour [MWh] Converter

Quick Reference

1 Milliwatt-hour (mWh) = 1.0000e-9 Megawatt-hour (MWh)

1 Megawatt-hour (MWh) = 1000000000 Milliwatt-hour (mWh)

How to Convert Milliwatt-hour to Megawatt-hour

1 mWh = 1.0000e-9 MWh
1 MWh = 1000000000 mWh

To convert Milliwatt-hour to Megawatt-hour, divide the value by 1000000000 (equivalently, multiply by 1.0000e-9). To convert Megawatt-hour back to Milliwatt-hour, multiply by 1000000000.

Example: convert 10 mWh to MWh:
10 mWh = 10 x 1.0000e-9 = 1.0000e-8 MWh

↔ Convert Megawatt-hour to Milliwatt-hour

Milliwatt-hour

Definition: A milliwatt-hour (symbol mWh) is a unit of energy equal to one-thousandth of a watt-hour. It represents a very small amount of energy.

History/origin: The milliwatt-hour is a derivative of the watt-hour, using the SI prefix 'milli-' to denote a factor of one-thousandth.

Current use: Milliwatt-hours are used in applications involving low-power electronics, such as sensors, small batteries, and medical devices.

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.
