Fraction to Percentage Converter

What is Fraction ↔ Percent?

A percentage is a fraction out of 100. Multiplying a fraction by 100 converts it to a percentage; writing a percentage over 100 and reducing converts it back.

How it works

Fraction → percent multiplies by 100 and simplifies, detecting repeating decimals; percent → fraction scales away the decimal point and reduces by the greatest common factor.
