Convert kilocalorie (IT)/minute to hectojoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to hectojoule/second [hJ/s], or Convert hectojoule/second to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Hectojoule/second
1 kcal/min = 0.6978 hJ/s
Example: convert 15 kcal/min to hJ/s:
15 kcal/min = 15 × 0.6978 hJ/s = 10.467 hJ/s

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.
Hectojoule/second
Hectojoule per second (hJ/s) is a unit of power representing one hundred joules of energy transferred or converted per second.
History/Origin
The unit hJ/s is derived from the SI unit joule (J) and the metric prefix hecto- (h), used to express larger quantities of energy transfer rate, particularly in scientific and engineering contexts. It has been used as an alternative to watts in certain fields, though watts are more standard.
Current Use
Hectojoule per second is occasionally used in scientific and engineering applications to quantify power, especially in contexts where larger energy transfer rates are involved. However, the watt (W) remains the standard SI unit for power, and hJ/s is less common in everyday use.
