Convert kilocalorie (IT)/minute to microjoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to microjoule/second [µJ/s], or Convert microjoule/second to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Microjoule/second
1 kcal/min = 69780000 µJ/s
Example: convert 15 kcal/min to µJ/s:
15 kcal/min = 15 × 69780000 µJ/s = 1046700000 µJ/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.
Microjoule/second
The microjoule per second (µJ/s) is a unit of power representing the rate of energy transfer or conversion, where one microjoule equals 10^-6 joules, transferred per second.
History/Origin
The microjoule per second originated from the need to measure very small power levels in scientific and engineering contexts, especially in fields like electronics and nanotechnology, as a scaled-down unit of the watt (joule per second).
Current Use
It is used in applications requiring precise measurement of low power levels, such as in microelectromechanical systems (MEMS), sensor technology, and research involving minute energy transfers.
