Milliwatt-hour [mWh] to Kilowatt-hour [kWh] Converter

Quick Reference

1 Milliwatt-hour (mWh) = 1.0000e-6 Kilowatt-hour (kWh)

1 Kilowatt-hour (kWh) = 1000000 Milliwatt-hour (mWh)

How to Convert Milliwatt-hour to Kilowatt-hour

1 mWh = 1.0000e-6 kWh
1 kWh = 1000000 mWh

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

Example: convert 10 mWh to kWh:
10 mWh = 10 x 1.0000e-6 = 1.0000e-5 kWh

↔ Convert Kilowatt-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.

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.
