How to Convert Decimals to Percents
Converting decimals to percentages is one of the simplest mathematical conversions. The word "percent" means "per hundred," so converting to a percentage means expressing the decimal as parts per hundred.
Quick Method
Multiply the decimal by 100 and add the % symbol
Formula: Percent = Decimal × 100
Example: Converting 0.75
- Start with 0.75
- Multiply by 100: 0.75 × 100 = 75
- Add the percent symbol: 75%

Alternative Method: Move Decimal Point
Instead of multiplying by 100, you can move the decimal point two places to the right:
- 0.75 → 75. → 75%
- 0.3 → 30. → 30%
- 1.25 → 125. → 125%
Frequently Asked Questions
How do you convert a decimal to a percent?
Multiply the decimal by 100 and add the percent symbol. For example, 0.45 × 100 = 45, so 0.45 = 45%.
What is 0.5 as a percentage?
0.5 equals 50%. When you multiply 0.5 by 100, you get 50, which means 50 percent or 50 parts per hundred.
Can percentages be greater than 100%?
Yes! Decimals greater than 1 convert to percentages greater than 100%. For example, 1.5 = 150% and 2.0 = 200%.
Why do you multiply by 100 to get a percent?
"Percent" literally means "per hundred." Multiplying by 100 converts the decimal to an equivalent value out of 100, which is what a percentage represents.
How do you convert a small decimal like 0.001 to a percent?
Use the same method: 0.001 × 100 = 0.1%. Small decimals result in percentages less than 1%.
What's the relationship between decimals, fractions, and percents?
They're all different ways to represent the same value. 0.5 (decimal) = 1/2 (fraction) = 50% (percent). Each form is useful in different contexts.
