Decimal to Fraction Converter
Convert a decimal to a simplified fraction, or a fraction to a decimal
Convert a decimal number to a simplified fraction and mixed number, or convert a fraction to its decimal value. Calculated locally in your browser as you type.

What this tool does
Decimals and fractions are two ways of writing the same value, but converting between them by hand means finding a common denominator and reducing it to lowest terms. This tool does that automatically in both directions: enter a decimal to get its simplest fraction and, where relevant, its mixed-number form; or enter a numerator and denominator to get the decimal value. The fraction search reduces every result to its lowest terms using the greatest common divisor.
How to use it
- Choose decimal-to-fraction or fraction-to-decimal mode.
- Enter the decimal, or the numerator and denominator.
- Read the simplified fraction, mixed number, or decimal result.

Frequently asked questions
- How are repeating decimals handled?
- The converter searches for the closest simple fraction up to a large denominator, which reproduces common repeating decimals like 0.333… as 1/3 accurately in practice.
- Are results always in lowest terms?
- Yes. Every fraction is reduced using the greatest common divisor of its numerator and denominator before it's shown.
- Is my input sent anywhere?
- No. The conversion happens locally in your browser.
