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

Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
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 watt in joule/second?
1 watt (W) = 1 joule/second (J/s).
How do you convert watt to joule/second?
Multiply the watt value by 1. For example, 25 W × 1 = 25 J/s.
What is 10 watt in joule/second?
10 W = 10 J/s.
Which unit is larger, the watt or the joule/second?
The joule/second is the larger unit: 1 W equals only 1 J/s.
