What does calorie (th)/second measure?

Calorie (th)/second quantifies power as the transfer of one thermochemical calorie of energy each second, where one thermochemical calorie equals exactly 4.184 joules.

Why convert calorie (th)/second to kilojoule/hour?

This conversion allows thermal power values defined every second to be expressed as energy rates per hour, facilitating comparisons in fields like HVAC, exercise physiology, and calorimetry.

How is kilojoule per hour defined?

Kilojoule per hour (kJ/h) measures the amount of energy transferred or consumed at a rate of 1,000 joules every hour, commonly used for low-to-moderate energy transfer rates over hourly periods.

Can this conversion be used for fluctuating power values?

No, the conversion assumes constant power output over the hour. Variable or transient power levels need more detailed timing measurements.
