Convert kilocalorie (IT)/minute to nanojoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to nanojoule/second [nJ/s], or Convert nanojoule/second to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Nanojoule/second
1 kcal/min = 69780000000 nJ/s
Example: convert 15 kcal/min to nJ/s:
15 kcal/min = 15 × 69780000000 nJ/s = 1046700000000 nJ/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.
Nanojoule/second
A nanojoule per second (nJ/s) is a unit of power representing the transfer or conversion of one nanojoule of energy per second.
History/Origin
The nanojoule per second is derived from the SI units of energy (joule) and time (second), with 'nano' indicating a factor of 10^-9. It is used in contexts requiring very small power measurements, especially in scientific and engineering fields.
Current Use
The nJ/s is used in scientific research, nanotechnology, and precise energy transfer measurements where extremely low power levels are involved, often in the context of nanoscale systems or experiments.
