What Is This Tool?
This unit converter allows you to translate power measurements from kilojoule per hour (kJ/h), which indicates energy transfer rates over hourly intervals, into calorie (IT) per second (cal/s), a unit used for thermal power based on the International Table calorie delivered every second.

Limitations
-
Kilojoule/hour is intended for small to moderate energy transfer over longer durations, which may limit direct application for fast transient powers
-
Conversion assumes consistent definitions of the International Table calorie to maintain accuracy
-
Comparisons between units require understanding of the underlying energy units and their timescales
-
Not suitable for units outside the specified kilojoule/hour and calorie (IT)/second measurements
Frequently Asked Questions
-
What does kilojoule/hour measure?
-
Kilojoule per hour measures power as the rate of energy transfer equal to 1,000 joules delivered or consumed each hour, often used for small to moderate energy transfer over time.
-
What is calorie (IT)/second used for?
-
Calorie (IT) per second is a unit of power measuring heat energy transferred every second using the International Table calorie, commonly applied in thermal power contexts and laboratory calorimetry.
-
Why convert kJ/h to cal/s?
-
Converting kilojoule/hour to calorie (IT)/second helps express power rates in calorie-based terms for scientific comparison, especially when dealing with older technical literature or specialized heat-transfer analysis.
Key Terminology
-
Kilojoule/hour [kJ/h]
-
A power unit describing energy transfer of 1,000 joules per hour, used to measure small to moderate energy rates over hourly periods.
-
Calorie (IT)/second [cal/s]
-
A power unit representing the rate of energy transfer equal to one International Table calorie per second, used for heat-transfer measurements.
-
Power
-
The rate at which energy is transferred, converted, or consumed, typically measured in watts or equivalent units.
