[Elecraft] K3 - REF CAL Question

[Don Wilhelm]

Paul,

You have to do that with your calculator :-) .
I never can remember when to add 32 and when to subtract 32, so I use a 
slightly different method which relies on the fact that both the F and C 
scales coincide at -40 deg.
Add 40 first - then multiply by 5/9 (multiply by 5 and divide by 9) if 
converting from F to C (9/5 when converting from C to F), then subtract 
40 and you will have the converted result.  Remembering whether to use 
5/9 or 9/5 is easy too - if the result you want is the C scale, the 
number will be smaller, so use 5/9.  When the result is in deg F, the 
number must be larger, so use 9/5.

73,
