Put another way, the zeroth law states that if systems A and B are in thermal equilibrium, and systems B and C are in thermal equilibrium, then systems A, B, and C are all in thermal equilibrium. Where ΔS = change in entropy, k = Boltzmann's constant, ln(W) = natural logarithm of W. In this context, W does not represent work—but rather, the total number of possible microstates the system can adapt. Instead of spending hours fiddling with Excel or Google Sheets (and never quite getting it right 🙄), simply list the materials and amounts that go into each of your products in Craftybase.
