Decimal to Fraction Converter
Turn any decimal into its simplest fraction.
Decimals as clean fractions
Fractions are often clearer than decimals for measurements and cooking, but converting by hand is fiddly. This tool finds the simplest fraction that matches your decimal.
The decimal 0.375 becomes 3/8; 1.25 becomes 5/4, or 1 1/4 as a mixed number. It reduces to lowest terms and shows the mixed-number form, so 0.375 is 3/8 and 1.25 is 5/4, or 1 1/4.
Exact and private
The conversion runs in your browser, so nothing you enter is uploaded.
