How decimal to percent converter works
A percent is just a fraction out of 100. To convert a decimal to a percent, multiply by 100 and append the % sign: 0.25 becomes 25%. To go the other way, drop the % and divide by 100: 25% becomes 0.25. The word "percent" literally means "per hundred".
This converter handles both directions. In "to" mode it multiplies the decimal by 100 and reports the percentage with its string form (e.g. "25%"). In "from" mode it strips a trailing % if present and divides by 100, so "25%" and 25 both become 0.25. Values greater than 1 (like 1.5) become percentages greater than 100 (150%).
Enter a value, pick a direction, and the tool returns the converted value. Use it for discounts, tax rates, test scores, growth rates, and any time you need to switch between decimal and percent notation.
