Fraction, Decimal & Percent Converter

Convert a fraction, decimal, or percentage to a simplified fraction, decimal value, percentage, and ratio-to-one representation.

Fraction, decimal, or percent

Simplified fraction

Decimal

Percent

Ratio to one

Repeating decimals need an approximation limit

The fraction search uses a denominator limit and a numerical tolerance. Exact typed fractions remain exact through the initial division, while long decimals may be represented by a nearby rational value. Review the denominator before using the result in a proof or exact calculation.

Worked example and guidance

Use Fraction, Decimal & Percent Converter with a checkable example

Example input

3/8

Expected output

0.375 = 37.5%

For the example above, the output should be read as an equivalent representation within the converter's supported subset. Fraction, Decimal & Percent Converter performs the browser-side transformation or calculation, but the mathematical convention, units, domain, and intended publishing format still come from your problem.

How to use it

Enter or paste a small known source value or notation before using a larger real-world example.
Choose the required options and run Fraction, Decimal & Percent Converter; keep the original input available for comparison.
Read the result together with its round-trip meaning and destination compatibility, then copy or export only after the check passes.

Useful for

Moving data into a publishing format
Checking a second representation
Creating copy-ready output for another application

Limits and checks

Not every source feature has an exact target equivalent
Whitespace and visual styling may change
Always test the output in the destination application

Fraction, Decimal & Percent Converter FAQ

Does Fraction, Decimal & Percent Converter upload my input?

No. The published tool runs in the browser. Avoid placing confidential material in share URLs or exported files that you later send elsewhere.

How should I verify a Fraction, Decimal & Percent Converter result?

Start with the worked example, inspect the round-trip meaning and destination compatibility, and compare one result with an independent calculation or representation.

What should I do when the input is rejected?

Reduce the input to the smallest failing source value or notation, check delimiters and supported syntax, then add the remaining structure back one step at a time.
