I think the problem is one of basic physics not basic chemistry.
Further to that I suggest the solution to the equation (ideally expressed in
British Thermal Units rather than these strange continental values) would hold
true only in laboratory conditions. Physics is a lot like economics in that
regard - many a good model is let down by the reality.
Rather than factoring in all the environmental variables, why not simply place
the containers holding solutions A and B in bath C filled with water at about
70F, equip bath C with an aquarium heater set to 70F, and turn it on an hour or
2 in advance?

Is it not also true that 1 degK = 1/100th of freezing to boiling ? If so
then the degK scale matches the degC scale. I agree there is nothing special
about that scale, but they do match. So when concerting degK to degC, you only
need to offset by 273.15, there is no scaling involved. When converting degK
to degF you must apply an offset and a scale.

Note that I said "relative to absolute zero". DegC IS only offset
relative to 0degK, whereas degF is scaled AND offset relative to 0degK.
Round not conceded.
Both are scaled. Both are offset.
At absolute zero the temperature is 0.00 in both
the Kelvin and Rankine scales
Offset:
0 Centigrade = 273 Kelvin or Absolute zero = -273C
0 Fahrenheit = 476 Rankine or Absolute zero = -476F
Scale:
1 degree centigrade is 1/100 of freezing to boiling
1 degree Fahrenheit 1/180 of freezing to boiling
There is nothing special about either scale.
