How to Convert Joule to Milliwatt-hourMilliwatt-hour

1 J = 0.2777777777777778 mWh
1 mWh = 3.6 J

Example: convert 38 J to mWh:
38 J = 38 x 0.2777777777777778 = 10.555555555555555 mWh

Joule

Definition: The joule (symbol: J) is the SI derived unit of energy. It is defined as the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).

History/origin: Named after James Prescott Joule, an English physicist. Joule experimentally determined the mechanical equivalent of heat.

Current use: Used universally in science and engineering to quantify energy, work, and heat. Examples include kinetic energy, potential energy, and heat content of materials.

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.
