Important Question, was lucky break

[Marcel Carey]

Roughly, at 440, a 4 cents deviation should equal 1 hertz plus or minus
fractions.
So, in my case this afternoon, the piano being 20 cents sharp was at 445.

Can someone clearly and simply explain the math involved in correlating
absolute pitch (in Hz) to pitch relationships (in cents)?

If anyone else is curious, as I was, Here is where Marcel tunes pianos (and
spinets, which may or may not--technically--be considered pianos ;- )
