Decimal to Fraction Converter
Convert a decimal number to its simplest fraction, including repeating decimals.
Decimals and fractions describe the same values, but each suits different work: fractions are exact and intuitive for cooking, woodworking and math, while decimals suit measurement and calculation. Converting between them by hand means finding a common denominator and simplifying — tedious, and genuinely tricky for repeating decimals like 0.3333.
Enter any decimal and this tool finds its simplest fraction, reducing to lowest terms and recognizing repeating decimals (0.333… becomes 1/3, not an unwieldy 3333/10000). It shows mixed numbers for values above one, ready for your recipe, blueprint or homework.
