Milliwatt-hour [mWh] to Joule [J] Converter

Quick Reference

1 Milliwatt-hour (mWh) = 3.6 Joule (J)

1 Joule (J) = 0.2777777778 Milliwatt-hour (mWh)

How to Convert Milliwatt-hour to Joule

1 mWh = 3.6 J
1 J = 0.2777777778 mWh

To convert Milliwatt-hour to Joule, multiply the value by 3.6. To convert Joule back to Milliwatt-hour, divide by 3.6.

Example: convert 10 mWh to J:
10 mWh = 10 x 3.6 = 36 J

↔ Convert Joule 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.

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 [mWh] to Joule [J] Converter

What is 1 mWh in J?

1 Milliwatt-hour (mWh) equals 3.6 J, and 1 J equals 0.2777777778 mWh.

How do I convert Milliwatt-hour to Joule?

Multiply by 3.6: 10 mWh × 3.6 = 36 J. The converter above does it for any value, with the precision you choose.

What is 100 mWh in J?

100 mWh = 360 J. Common amounts are listed on this page, each with its own step-by-step page.

Is a Milliwatt-hour bigger than a Joule?

Yes. 1 mWh = 3.6 J, so the same quantity becomes a larger number when written in J.
