Tomes,

You probably entered the aspect ratio as 75 where, with this formula you
need to enter it as .75. I simplified the formula to use the aspect ratio
without the decimal point and also condensed all of the conversions coming
up with A2*B2/1270+C2 for the formula. Remember, with this formula, you
enter the aspect ratio without the decimal point(i.e. 75 instead of .75).

Well, 75 is a percent so you really use .75, so 225 * .75 = 168.75 x 2 =
337.5 / 25.4 = 13.29 + 15 = 28.29

Sorry, I thought everybody knew that an aspect ratio was a percent. Maybe
that's because I think that any ratio is a percent.
