What Is This Tool?
This converter helps you change heat flux density measurements from calorie (th)/minute/square centimeter, based on thermochemical calorie per minute, to calorie (IT)/second/square centimeter, which uses the international-table calorie per second. It supports accurate comparison and interpretation of thermal data with different calorie definitions.

Tips & Best Practices
-
Confirm whether thermochemical or international-table calorie applies in your data source
-
Ensure consistent time units when comparing or integrating results
-
Use this converter primarily for legacy or discipline-specific calorie-based measurements
-
Double-check conversions when translating from calorie units to SI units
-
Maintain documentation of original and converted units in experimental records
Limitations
-
Distinct calorie definitions require clear contextual understanding to avoid mistakes
-
Conversion involves adjusting time units, which may introduce errors if mishandled
-
Decreasing use of calorie units in favor of SI limits modern applicability
-
Precision may vary when integrating with contemporary joule-based data
-
Not suitable for conversions beyond the specified calorie heat flux units
Frequently Asked Questions
-
Why are there different calorie units in this conversion?
-
The thermochemical calorie and international-table calorie differ slightly in energy definition, so conversions must distinguish these units to maintain accuracy.
-
Can this tool convert heat flux density to SI units?
-
This tool specifically converts between two calorie-based units; for SI unit conversions, specialized tools should be used.
-
When should I use calorie (IT)/second/square centimeter instead of calorie (th)/minute/square centimeter?
-
Use calorie (IT)/second/square centimeter mainly in older literature or discipline-specific contexts where the international-table calorie and per-second time base are standard.
Key Terminology
-
Calorie (th)/minute/square centimeter
-
A heat flux density unit expressing power per unit area using the thermochemical calorie transferred per minute across one square centimeter.
-
Calorie (IT)/second/square centimeter
-
A heat flux density unit representing power per unit area based on the international-table calorie transferred per second across one square centimeter.
-
Heat flux density
-
The measure of heat power transferred per unit area, often expressed in calorie-based or joule-based units.
