Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to exawatt [EW], or Convert exawatt to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Exawatt
1 kcal/min = 6.978e-17 EW
Example: convert 15 kcal/min to EW:
15 kcal/min = 15 × 6.978e-17 EW = 1.0467e-15 EW

Kilocalorie (It)/minute
A unit of power representing the energy expended or transferred at a rate of one kilocalorie per minute.
History/Origin
The kilocalorie (kcal) has historically been used to measure energy in food and nutrition, while the minute as a time unit has been standard in timekeeping. Combining these, kcal/min was used to quantify power, especially in contexts like metabolic rates and energy expenditure, before the widespread adoption of the watt as the SI unit of power.
Current Use
The kcal/min is primarily used in fields such as physiology and sports science to express rates of energy expenditure, though it is less common today with the adoption of the watt (W) as the standard SI unit of power.
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.
