Percent, Decimal, and Fraction Converter
Use this converter when you need the same value in a different form before you multiply. Percents are decimals times 100. Fractions are a numerator over a denominator, then that quotient times 100.
How this is calculated
Moving between percent and decimal is a multiply or divide by 100. A fraction becomes a decimal first, then a percent.
percent = decimal × 100 = (numerator / denominator) × 100
- From percent to decimal, divide by 100. 25% = 0.25.
- From decimal to percent, multiply by 100. 0.125 = 12.5%.
- From a fraction, divide then multiply by 100. 3/8 = 0.375 = 37.5%.
Once you have the decimal, finding a percent of a number is just multiplication. 0.25 × 80 = 20, which is 25% of 80.
