About Decimal to Percent
Fractions, decimals and percentages describe the same thing in three different languages: a share of a whole. School marks and discounts use percentages, measurements and money use decimals, and recipes, spanners and shares of ownership stay in fractions.
This page converts decimals to percents and shows the working, so the method is clear the next time you have to do it on paper. Mixed numbers such as 1 1/2 are accepted, and repeating decimals are matched to the closest simple fraction rather than left as a long string of digits.
How it works
A fraction, a decimal and a percentage are three ways of writing the same quantity. Turning decimals into percents takes three steps:
- Multiply by 100.
- Add the % sign.
- Move the decimal point two places to the right for the same result.
Going the other way is Percent to Decimal.
