Milliwatt-hour [mWh] to Watt-hour [Wh] Converter

Quick Reference

1 Milliwatt-hour (mWh) = 0.001 Watt-hour (Wh)

1 Watt-hour (Wh) = 1000 Milliwatt-hour (mWh)

How to Convert Milliwatt-hour to Watt-hour

1 mWh = 0.001 Wh
1 Wh = 1000 mWh

To convert Milliwatt-hour to Watt-hour, divide the value by 1000 (equivalently, multiply by 0.001). To convert Watt-hour back to Milliwatt-hour, multiply by 1000.

Example: convert 10 mWh to Wh:
10 mWh = 10 x 0.001 = 0.01 Wh

↔ Convert Watt-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.

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.
