Fraction Chart: Decimals and Percents
This fraction chart lists every fraction for a denominator you choose, from halves to sixty-fourths, with its decimal, percent and inches-to-millimeter value. It is handy for school, woodworking, sewing, drill bits and tape measure readings. Use the decimal to fraction finder to turn any decimal such as 0.3125 into its nearest fraction with a maximum denominator, and see how close it is. The chart shows reduced forms too, so 2/8 appears as 1/4. Everything runs in your browser and the table can be exported to CSV.
