As has already been discussed in this thread, it has been standard practice for decades (probably in the hundreds of years, now) to "tune" or calibrate your tuning fork for the temperature at which you plan on using it. Even slight variations in temperature will change the frequency of the fork. Perhaps yours is at 440 at 20C, but I'll guarantee you that every piano you tune is not in a 20C environment. Your fork will be off in those settings unless you have a practice for equilibrating your fork to 20C prior to setting the A. -- William R.
