Decimal and fraction converter
Students, cooks, and engineers all bump into the same need: turning a terminating decimal like 0.625 into a clean fraction (5/8), or checking that 7/16 on a tape measure matches a calculator readout. This tool does both directions on one page so you can cover related searches together.

Frequently asked questions
- How do you convert a decimal to a fraction?
- Write the decimal as an integer over a power of 10 based on how many digits follow the decimal point (e.g. 0.375 = 375/1000), then divide numerator and denominator by their greatest common divisor to simplify (375/1000 = 3/8).
- Does this tool support mixed numbers?
- In fraction-to-decimal mode you can enter mixed numbers like 1 3/4. In decimal-to-fraction mode the result is shown both as an improper fraction and as a mixed number when applicable.
- Why is 0.1 shown as 1/10 and not 1/3?
- Your input is parsed exactly as a finite decimal. One third is 0.333… repeating; it cannot be represented exactly with a finite decimal expansion, so enter it as the fraction 1/3 to see its decimal approximation instead.
- How do you convert a fraction to a decimal?
- Divide the numerator by the denominator. For example, 3 ÷ 8 = 0.375. This tool does that division for you. For fractions that do not terminate in decimal form, the result is shown to a fixed number of places (truncated), while the fraction remains exact.
- What does simplifying a fraction (lowest terms) mean?
- A fraction is in lowest terms when the numerator and denominator share no common factor other than 1. This tool divides both by their greatest common divisor (GCD), so results like 375/1000 become 3/8.
- Are there limits on decimal input or how many places are shown?
- You can enter up to 16 digits after the decimal point. When converting fractions to decimals, the calculator shows up to 14 decimal places (truncated). Very long repeating decimals may look rounded even though the fraction you typed is still exact.
- Is this converter free?
- Yes. Everything runs locally in your browser; nothing is uploaded to a server.
Tips
- Decimals are parsed from the characters you type, so values like
0.375become exact rationals before simplifying — no floating-point rounding surprises. - For repeating decimals, start from the fraction form (or use a dedicated repeater tool later); we show fraction → decimal to a fixed number of places.
- Negative values are supported; you can also wrap negatives in parentheses when entering decimals (e.g.
(0.5)).
