Fractions to Decimal Conversion Table

Since I deal a lot with designing artwork in US measurements (fractions) using Illustrator and Photoshop, more often than not I have to break out a calculator to determine the decimal value of a fractional measurement.

Lets say I need to create a document that is 4 inches wide by 3 7/16 inches high. Obviously 4 inches needs no conversion, but then you have the 3 7/16 inches measurement. First you take 1, divide it by 16, then multiply the result by 7… what a pain.

So I have thrown together a quick reference guide that start at 1/64 and goes up to 63/64 with each variation in between. Bookmark or print this page to save a copy for your own personal reference. The most common fractions for my purposes are outlined in bold.
