Convert joule/hour to exawatt
Enter a value below to convert joule/hour [J/h] to exawatt [EW]. Reverse conversion: Convert exawatt to joule/hour.
1 J/h = 2.7778e-22 EW. To convert joule/hour to exawatt, multiply the value by 2.7778e-22; to go the other way, divide by it (1 EW = 3.6000e+21 J/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Joule/hour: Definition and Use
A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.
History/Origin
The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.
Current Use
Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.
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.
