Fraction to Percent Converter

About this calculator

A fraction expresses a part-to-whole relationship as two integers, a numerator over a denominator, while a percentage expresses the same ratio out of 100. The conversion is simple division followed by scaling: percent = (numerator ÷ denominator) × 100, so 3/4 becomes 0.75 × 100 = 75%. When the division doesn't terminate cleanly, the result is typically rounded to one or two decimal places.

This conversion is one of the most common tasks in basic arithmetic, taught in schools worldwide as students move between fraction and percentage notation for grades, test scores, and word problems. It also comes up constantly outside the classroom — figuring out a discount from a "1/3 off" sale, converting a recipe ratio, or reading survey results that mix both formats.
