Agreed in principle, but I don't think that 273.15 is a 'factor'
precisely :-)
We have just spent several minutes discussing a suitable name; one
suggestion was on the lines of Zero_Celsius_In_Kelvins.
procedure P (Temperature : Float);
-- Temperature is in Kelvins
C : Float;
-- in Celsius
...
P (Temperature => C + Zero_Celsius_In_Kelvins);
which is pretty icky. Perhaps derived or even private types would be
interesting. Perhaps just conversion functions, inline if you like?
function To_Kelvins (Temperature_In_Celsius : Float) return Float;
