Fraction to Decimal Converter

About this calculator

This tool performs the long-division method a fraction represents: dividing the numerator by the denominator to get a decimal, then multiplying by 100 for the percentage. Some fractions terminate cleanly (like 1/4 = 0.25) while others repeat forever (like 1/3 = 0.333...), and the calculator rounds these to a practical number of decimal places.

It's used by students checking homework, cooks converting recipe measurements, and tradespeople reading imperial measurements like 3/8" or 5/16" on a tape measure or drill bit set, where a decimal equivalent is often easier to compare or type into a machine than the fraction itself.
