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

Quick Reference

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

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

How to Convert Kilowatt-hour to Milliwatt-hour

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

To convert Kilowatt-hour to Milliwatt-hour, multiply the value by 1000000. To convert Milliwatt-hour back to Kilowatt-hour, divide by 1000000.

Example: convert 10 kWh to mWh:
10 kWh = 10 x 1000000 = 10000000 mWh

↔ Convert Milliwatt-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.

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.
