Entropy in Thermodynamics Formulas
Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. And is denoted by S. Entropy is usually measured using the Joule per Kelvin for Entropy. Note that the value of Entropy is always negative.

FAQ
What is the Entropy?
Entropy is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Entropy is usually measured using the Joule per Kelvin for Entropy. Note that the value of Entropy is always negative.
Can the Entropy be negative?
Yes, the Entropy, measured in Entropy can be negative.
What unit is used to measure Entropy?
Entropy is usually measured using the Joule per Kelvin[J/K] for Entropy. Joule per Kilokelvin[J/K], Joule per Fahrenheit[J/K], Joule per Celsius[J/K] are the few other units in which Entropy can be measured.
