It's a very conventional way to define temperature in thermodynamics/physics.
Fun fact, you could create infinite energy if you could create a Carnot thermodynamical cycle that crosses + and - temperatures. That was a big issue with the concept of negative temperatures, until someone proved that it's impossible to create such a cycle to begin with.
