In Hp48/49/50 series, the convertion's, are incompatible, the K to °F and viceversa.

And your example, to 5_°F+5_°F isn't ... 469.67_°F.
The correct result, is ... 10_°F

Kind Regards.

I can confirm that a 48SX does indeed return 469.67_°F, it would seem that it messes up the units but not in an entirely random manner because 5_°F is 464.67_°R so it would seem that for some reason it converts to °R to make the calculation but does not convert back, 469.67_°R = 10°F

It does a similar thing with °C but converts to Kelvin in that case, adding degrees Rankine or Kelvin work as expected.
