Beats vs cycles vs cents

[Jason Kanter]

If A4 is 8 beats flat, that means it is vibrating at 432 cycles instead of
440, which is 31.8 cents flat.
If C4 is 8 beats flat, that means it is vibrating at 253.63 cycles instead
of 261.63, which is 53.73 cents flat.
If A4 is 8 cents flat, that means it is vibrating at 437.97 cycles instead
of 440, creating about 2 beats per second.
If C4 is 8 cents flat, that means it is vibrating at 260.42 cycles instead
of 261.63, creating about 1.2 beats per second.

There is no across-the-board equality between beats and cents.
