Tips & Best Practices
-
Ensure units are correctly selected before conversion
-
Use this tool for average power rates over specified time intervals
-
Be cautious when converting transient or instantaneous power values
-
Understand the exact definition of the thermochemical calorie for accurate results
Limitations
-
Conversion assumes the thermochemical calorie definition only
-
Different calorie definitions require adjustment outside this tool
-
Power units average energy over different time intervals; conversion may not suit instantaneous rates
-
Possible rounding errors for very low power values when converting to kilojoule/hour
Frequently Asked Questions
-
What is a calorie (th)/minute unit?
-
It is a power unit representing one thermochemical calorie (exactly 4.184 joules) transferred per minute, commonly used in calorimetry and metabolic rate measurements.
-
Why convert calorie (th)/minute to kilojoule/hour?
-
Converting to kilojoule/hour allows expressing energy transfer rates over longer hourly periods, which is useful in physiology, building physics, and energy analysis.
-
Can I use this conversion for dietary calories?
-
No, this tool assumes the thermochemical calorie definition. Dietary calorie conversions need caution as their values differ.
