Convert milliwatt to joule/second
Please provide values below to convert milliwatt [mW] to joule/second [J/s], or Convert joule/second to milliwatt.
1 mW = 0.001 J/s. To convert milliwatt to joule/second, multiply the value by 0.001; to go the other way, divide by it (1 J/s = 1000 mW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mW = 0.001 J/s
- 1 J/s = 1000 mW
- 10 mW = 0.01 J/s
- 100 mW = 0.1 J/s
How to Convert Milliwatt to Joule/second
1 mW = 0.001 J/s
Example: convert 15 mW to J/s:
15 mW = 15 × 0.001 J/s = 0.015 J/s

Milliwatt
A milliwatt (mW) is a unit of power equal to one thousandth of a watt, used to measure small amounts of power.
History/Origin
The milliwatt was introduced as part of the metric system to provide a convenient unit for measuring low power levels, especially in electronics and telecommunications, with its usage expanding alongside the adoption of the watt as the standard power unit.
Current Use
Milliwatts are commonly used today in electronics, audio equipment, and wireless communication devices to specify power levels, such as in battery-powered devices, LED brightness, and signal transmission power.
Joule/second
The joule per second (J/s) is a unit of power representing the rate at which energy is transferred or converted, equivalent to one watt.
History/Origin
The joule per second has been used as a measure of power since the adoption of the SI system, where the watt (W) became the standard unit of power, with 1 J/s = 1 W.
Current Use
J/s is primarily used in scientific and engineering contexts to quantify power, especially in physics and electrical engineering, often interchangeably with watts.
Frequently Asked Questions
What is 1 milliwatt in joule/second?
1 milliwatt (mW) = 0.001 joule/second (J/s).
How do you convert milliwatt to joule/second?
Multiply the milliwatt value by 0.001. For example, 25 mW × 0.001 = 0.025 J/s.
What is 10 milliwatt in joule/second?
10 mW = 0.01 J/s.
Which unit is larger, the milliwatt or the joule/second?
The joule/second is the larger unit: 1 mW equals only 0.001 J/s.
