Entropy converter

erg per kelvin to joule per kelvin

Convert erg per kelvin (erg/K) to joule per kelvin (J/K). Use an editable entropy converter, conversion formula, and reference table.

1e-7

1 erg/K = 1e-7 J/K

Calculated in your browser

Conversion formula

J/K = erg/K × 1e-7

One erg per kelvin equals 1e-7 joule per kelvin. Multiply your value in erg per kelvin by this factor to get joule per kelvin. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 erg per kelvin:
5 × 1e-7 = 5e-7 J/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 erg per kelvin is 1e-7 base units; one joule per kelvin is 1 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 erg/K to J/K?

Multiply the quantity in erg/K by 1e-7. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the joule per kelvin to erg per kelvin converter.
