Cents to Hertz Conversion Chart

[David Ilvedson]

My understanding was 50 cents flat is a 1/4 tone flat.  100 cents is 
a 1/2 step flat.  If I want to tune a piano to A442 I tune about 8 
cents above A440...Chickering made a Quarter Grand that has 
stamped on the plate: "International Pitch = 435"  If I want to leave 
that piano at 435 I tune it about 20 cents flat of 440.
