Convert joule/second to milliwatt
Please provide values below to convert joule/second [J/s] to milliwatt [mW], or Convert milliwatt to joule/second.
1 J/s = 1000 mW. To convert joule/second to milliwatt, multiply the value by 1000; to go the other way, divide by it (1 mW = 0.001 J/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 J/s = 1000 mW
- 1 mW = 0.001 J/s
- 10 J/s = 10000 mW
- 100 J/s = 100000 mW
How to Convert Joule/second to Milliwatt
1 J/s = 1000 mW
Example: convert 15 J/s to mW:
15 J/s = 15 × 1000 mW = 15000 mW

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.
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.
Frequently Asked Questions
What is 1 joule/second in milliwatt?
1 joule/second (J/s) = 1000 milliwatt (mW).
How do you convert joule/second to milliwatt?
Multiply the joule/second value by 1000. For example, 25 J/s × 1000 = 25000 mW.
What is 10 joule/second in milliwatt?
10 J/s = 10000 mW.
Which unit is larger, the joule/second or the milliwatt?
The joule/second is the larger unit: 1 J/s = 1000 mW.
