What is the calorie (IT)/hour unit used for?

It is used to measure very small steady heat flow rates, commonly in laboratory calorimetry, thermal tests, and historical data.

How is the conversion rate determined?

It is based on the definition of one International Table calorie equivalent to 4.1868 joules, converted per hour to kilojoules.

Can this converter be used for other calorie definitions?

No, this tool specifically converts using the International Table calorie (cal_IT) and not other calorie variants.

Why convert calorie (IT)/hour to kilojoule/hour?

Converting to kilojoule/hour enables better comparison with SI units and facilitates understanding of energy transfer over hourly intervals.
