thermochemical calorie per kelvin to erg per kelvin
Convert thermochemical calorie per kelvin (cal/K) to erg per kelvin (erg/K). Use an editable entropy converter, conversion formula, and reference table.
1 cal/K = 41,840,000 erg/K
Conversion formula
One thermochemical calorie per kelvin equals 41,840,000 erg per kelvin. Multiply your value in thermochemical calorie per kelvin by this factor to get erg per kelvin. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 thermochemical calorie per kelvin:5 × 41,840,000 = 209,200,000 erg/K

About these measurements
Entropy is a thermodynamic state quantity with units of energy per temperature.
The base reference used here is the joule per kelvin. One thermochemical calorie per kelvin is 4.184 base units; one erg per kelvin is 1e-7 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert cal/K to erg/K?
Multiply the quantity in cal/K by 41,840,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the erg per kelvin to thermochemical calorie per kelvin converter.
