Convert calorie (IT)/hour to exawatt
Please provide values below to convert calorie (IT)/hour [cal/h] to exawatt [EW], or Convert exawatt to calorie (IT)/hour.
How to Convert Calorie (It)/hour to Exawatt
1 cal/h = 1.163e-18 EW
Example: convert 15 cal/h to EW:
15 cal/h = 15 × 1.163e-18 EW = 1.7445e-17 EW

Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
Exawatt
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.
