Examples
-
5 kJ/kg/°C = 5 × 0.2388458966 = 1.1942 kcal(IT)/kg/K
-
10 kJ/kg/°C = 10 × 0.2388458966 = 2.3885 kcal(IT)/kg/K
Common Use Cases
-
Heating and cooling system design including HVAC and thermal storage
-
Thermal process engineering tasks such as pasteurization of foods
-
Thermal balance and chemical process calculations using steam tables
-
Building thermal load estimations in regions using calorie-based units
-
Translating legacy engineering data from calorie units to SI units
Tips & Best Practices
-
Remember that degree Celsius and kelvin temperature increments are equivalent in this context
-
Verify which calorie definition (International Table calorie) applies in your data
-
Use this tool to ensure consistency when working with mixed unit data sources
-
Double-check input values to avoid incorrect conversions due to unit confusion
-
Consider the context of your engineering design to choose appropriate units
Limitations
-
The tool assumes equivalence of °C and K increments but does not adjust absolute temperatures
-
Conversions are specific to the International Table calorie unit only
-
Using other calorie definitions requires additional conversion adjustments
-
The tool is limited to specific heat capacity units stated and does not convert unrelated units
-
Users must interpret results considering the particular industry context
Frequently Asked Questions
-
Why are kilojoule/kilogram/°C and kilojoule/kilogram/K units considered numerically identical?
-
Because the degree Celsius and the kelvin have the same increment size, their specific heat capacity values are numerically equivalent.
-
When should I use kilocalorie (IT)/kilogram/K instead of kilojoule/kilogram/°C?
-
Use kilocalorie (IT)/kilogram/K when working with older engineering data, legacy documentation, or thermal process designs that utilize calorie-based units.
-
Can this conversion be applied to calories other than the International Table calorie?
-
No, this tool specifically converts using the International Table calorie unit; other calorie definitions require separate adjustments.
Key Terminology
-
Kilojoule/kilogram/°C
-
A unit expressing the heat energy in kilojoules needed to raise the temperature of one kilogram of a substance by one degree Celsius.
-
Kilocalorie (IT)/kilogram/K
-
A unit representing the heat energy in International Table kilocalories required to raise the temperature of one kilogram of a substance by one kelvin.
-
Specific Heat Capacity
-
The amount of heat energy per unit mass needed to change a substance's temperature by one degree Celsius or kelvin.
