then the degK scale matches the degC scale.
Agreed
When converting degK to degF you must apply an offset and a scale.
The equivalent absolute zero scale for Fahrenheit is Rankine, not
Kelvin.
When converting between Celsius and Fahrenheit there is both an offset and a
scale change.
When converting between Kelvin and Rankine there is only a scale change.
When converting between Celsius and Kelvin there is only an offset change,
when converting between Fahrenheit and Rankine there is only an offset
change.
I think we are saying the same thing... the usual outcome of
most usenet parley.
Converting Fahrenheit to Kelvin isn't very common in practice,
about as common as converting Celsius to Rankine. In both cases
there is an offset and scale change.
If you are in a Fahrenheit world you use Rankine. Rankine is
common in thermodynamics and fluid and thermal engineering
because it goes with such wonders as the British Thermal Unit
and steam tables. BTU's, calories, joules and foot-pounds
- a real mess.
