What Is This Tool?
This converter allows users to change power units from calorie (IT) per minute to calorie (th) per second, facilitating the translation between international-table calorie energy rates and thermochemical calorie energy rates commonly used in laboratory and thermal engineering settings.
How to Use This Tool?
-
Enter the power value measured in calorie (IT) per minute into the input field.
-
Select the output unit as calorie (th) per second.
-
Click the convert button to view the equivalent power in the desired unit.
Key Features
-
Converts power units between calorie (IT)/minute and calorie (th)/second accurately based on defined conversion rates.
-
Supports applications in laboratory calorimetry, thermal engineering, physiology, and HVAC process calculations.
-
Browser-based and easy-to-use tool enabling quick unit translation without complex calculations.
Examples
-
Convert 5 cal (IT)/min: 5 × 0.0166778203 = 0.0833891015 cal (th)/s
-
Convert 10 cal (IT)/min: 10 × 0.0166778203 = 0.166778203 cal (th)/s
Common Use Cases
-
Reporting heat release or absorption rates in laboratory calorimetry experiments.
-
Specifying heating power of small laboratory heaters or hot plates in thermal engineering.
-
Reporting metabolic rates in physiology and exercise science on a minute scale.
-
Converting legacy thermal power values into SI-based thermochemical calorie units for HVAC or process engineering.
Tips & Best Practices
-
Ensure proper unit selection to avoid confusion between international-table and thermochemical calorie definitions.
-
Use the converter to integrate historical data with modern thermochemical-based measurements.
-
Consider the differences in time scales when comparing results (minute vs second).
-
Account for potential energy losses that the conversion assumes are ideal and negligible.
Limitations
-
Different calorie definitions (international-table vs thermochemical) can impact conversion precision.
-
The conversion is based on ideal conditions and does not consider actual energy losses.
-
Comparisons across units should be done carefully due to time unit differences and calorie definitions.
Frequently Asked Questions
-
What does calorie (IT)/minute measure?
-
It measures power as the rate of one international-table calorie of energy transferred per minute, often used to express small continuous heat rates.
-
Why convert calorie (IT)/minute to calorie (th)/second?
-
Conversion enables comparison and integration of heat transfer data based on different calorie definitions and time scales used in various scientific and engineering contexts.
-
Are the calorie definitions identical between these units?
-
No, the international-table calorie differs from the thermochemical calorie, affecting the conversion and precision between these units.
Key Terminology
-
Calorie (IT)/minute
-
A power unit representing the transfer of one international-table calorie per minute, often used for small-scale heat transfer rates.
-
Calorie (th)/second
-
A power unit representing the transfer of one thermochemical calorie of energy per second, where 1 cal(th)/s equals 4.184 watts.
-
Thermochemical calorie
-
A calorie unit defined as exactly 4.184 joules, used in thermochemical energy calculations.
