Why do you need to convert Hz into cents? Apart from the rough rule of thumb that 1 Hz=4 cents @A440, 2 cents @880, etc., no table can tell you what you're asking to the degree of accuracy you require, for two reasons: 1) each piano has a different scale and 2) two good tuners might choose slightly different widths of temperament octave. If you are using it to check temperaments, for each piano you will need to calculate an individual amount of cents offset for each note (except A440), based upon the width chosen for the temperament octave. I can help with that if you need; it's not difficult. Second question: does the little window display all the harmonics, or just octaves? Finally, I don't think you can get an accurate enough reading with a StroboTuner, although you can certainly get a pretty good idea of how smooth your temperament is. Is there someone around with an AccuTuner? If not, good results can be obtained with a little more effort with an old Sight-O-Tuner, and it's not terribly expensive used. Let me know if I can help further. Bob Davis
