What is the kilojoule unit used for?

Kilojoule is an SI-derived unit of energy used in scientific contexts such as chemical thermodynamics, nutrition, and engineering to quantify work, heat, and other energy transfers.

Why convert kilojoule to kilocalorie (th)?

Converting kilojoules to kilocalorie (th) helps interpret energy values in food labeling, dietary studies, and engineering contexts where thermochemical calories are commonly used.

Is kilocalorie (th) the same as other calorie units?

No, kilocalorie (th) is defined as exactly 4,184 joules and may differ slightly from other calorie definitions, impacting conversion precision.

Click the convert button to obtain the equivalent energy in kilocalorie (th).
Use the results to assist with dietary, nutritional, or engineering energy calculations.

Key Features

Converts kilojoule units to thermochemical kilocalories accurately based on defined conversion rates.
Useful for interpreting energy values in nutritional labels and dietary planning.
Applicable in chemical thermodynamics and thermal engineering calculations.
Browser-based and easy to use with no installation required.
Provides clear examples for practical conversion scenarios.

Examples

Convert 10 kJ: 10 × 0.2390057361 = 2.390057361 kcal (th)
Convert 50 kJ: 50 × 0.2390057361 = 11.950286805 kcal (th)

Common Use Cases

Interpreting energy content on food labels where kilojoules need to be converted to calories.
Performing metabolic studies and dietary planning involving energy intake measurements.
Calculating heat quantities and enthalpies in chemical thermodynamics and thermal engineering.
Referencing energy content in older engineering literature using thermochemical calories.

Tips & Best Practices

Ensure the energy values input are in kilojoules before conversion.
Understand that kilocalorie (th) uses a specific definition distinct from other calorie types.
Use this converter as a guide and consult precise SI units when accuracy is critical.
Check if your application prefers SI units exclusively as some contexts may limit thermochemical calorie use.

Limitations

Variations in calorie definitions can impact the precision of conversions.
Some fields require strictly SI units, so kcal (th) might not be accepted.
Experimental data rounding can influence the accuracy of results.
