That math is so simple, even I can do it.

A 135mm film frame is 24x36 mm. Convert to inches & you get 0.94 x 1.42

Scan @ 4,000 dpi = 3760 x 5680 = 21,356,800

Divide twice by 1024 gives 20.37 MP

I chose 4,000 dpi because that's what Nikon said the Coolscan 9000 could do.

I remember a PDML post once upon a time that claimed it would take
about 20-25 MP for digital to equal the IQ of film.
