Convert kilocalorie (IT)/minute to attojoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to attojoule/second [aJ/s], or Convert attojoule/second to kilocalorie (IT)/minute.
1 kcal/min = 6.9780e+19 aJ/s. To convert kilocalorie (IT)/minute to attojoule/second, multiply the value by 6.9780e+19; to go the other way, divide by it (1 aJ/s = 1.4331e-20 kcal/min). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kcal/min = 6.9780e+19 aJ/s
- 1 aJ/s = 1.4331e-20 kcal/min
- 10 kcal/min = 6.9780e+20 aJ/s
- 100 kcal/min = 6.9780e+21 aJ/s
How to Convert Kilocalorie (It)/minute to Attojoule/second
1 kcal/min = 6.978e+19 aJ/s
Example: convert 15 kcal/min to aJ/s:
15 kcal/min = 15 × 6.978e+19 aJ/s = 1.0467e+21 aJ/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.
Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
