Frequently Asked Questions
-
What does 1 calorie (IT)/second represent?
-
It represents the power corresponding to the transfer of one International Table calorie of energy per second, typically used to express thermal power or heat-transfer rates.
-
Why convert calorie (IT)/second to nanowatts?
-
To translate historical thermal power values into extremely low power units suitable for modern electronic and photonic measurements.
-
Can this conversion be used for all calorie units?
-
No, this conversion specifically applies to the International Table calorie per second, and variations in calorie definitions should be considered.
