Not suitable for applications outside direct thermal-to-nanoscale power rate translation.
Frequently Asked Questions
-
What does one kilocalorie (th)/minute represent in terms of power?
-
It is a unit of thermal power representing the rate of energy transfer corresponding to one thermochemical kilocalorie delivered every minute.
-
Why convert from kilocalorie (th)/minute to nanojoule/second?
-
This conversion allows expressing thermal or metabolic power rates into very small power units used in electronics, photonics, and sensor applications.
-
Are the conversion results easy to interpret?
-
Because of the large difference in scale, the converted values are extremely large and may need careful interpretation and proper tools.
