I just came across an issue when solving a simple thermodynamics problem. Steam enters a turbine at 140 psia and 1000 F and expands isentropically to 2psia. When I try to determine the exit temperature, the problem occurs. If I set the units for the problem to FPS, I get the answer in F. The problem is that the numerical value is wrong. The numerical value corresponds to degree R, not F. The numerical value given is 585 F, it should be 585 R.  If I set the problem to SI units, the answer is in K. The answer given is 325 K.  I can then convert it to degree F. This way I get the correct answer.
