What does calorie (IT)/hour measure?
-
Calorie (IT)/hour measures the rate of energy transfer representing small steady heat flow rates, based on the International Table calorie.
-
Why convert calorie (IT)/hour to picowatt?
-
Converting helps express small heat flow rates in SI units for compatibility with advanced scientific instruments and modern technical literature.
-
Can this converter be used for large power values?
-
This converter is intended for very small power measurements and may not be suitable for large-scale power values.
Key Terminology
-
Calorie (IT)/hour [cal/h]
-
