Convert joule/second to exawatt
Enter a value below to convert joule/second [J/s] to exawatt [EW]. Reverse conversion: Convert exawatt to joule/second.
1 J/s = 1.0000e-18 EW. To convert joule/second to exawatt, multiply the value by 1.0000e-18; to go the other way, divide by it (1 EW = 1.0000e+18 J/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Joule/second to Exawatt: Quick Reference
- 1 J/s = 1.0000e-18 EW
- 1 EW = 1.0000e+18 J/s
- 10 J/s = 1.0000e-17 EW
- 100 J/s = 1.0000e-16 EW
How to Convert Joule/second to Exawatt
1 J/s = 1e-18 EW
Example: convert 15 J/s to EW:
15 J/s = 15 × 1e-18 EW = 1.5e-17 EW

Joule/second: Definition and Use
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.
Exawatt: Definition and Use
An exawatt (EW) is a unit of power equal to 10^18 watts.
History/Origin
The exawatt is part of the SI prefix system, introduced to represent extremely large power quantities, especially in theoretical physics and astrophysics, as the need to express vast energy outputs grew.
Current Use
Exawatts are primarily used in scientific contexts to describe the power output of large-scale phenomena such as stars and cosmic events; they are rarely used in everyday measurements.
Joule/second to Exawatt: Frequently Asked Questions
What is 1 joule/second in exawatt?
1 joule/second (J/s) = 1.0000e-18 exawatt (EW).
How do you convert joule/second to exawatt?
Multiply the joule/second value by 1.0000e-18. For example, 25 J/s × 1.0000e-18 = 2.5000e-17 EW.
