How to Convert a Decimal to a Percentage
To convert a decimal to a percentage, multiply the decimal by 100 and add the percent sign (%).
Decimal to Percentage Formula
Percentage = Decimal × 100
For example:
0.25 × 100 = 25%
Therefore:
0.25 = 25%
This is the basic decimal to percent conversion and works for positive and negative decimals as well.
How to Calculate Decimal as a Percentage
To turn a decimal into a percentage, simply multiply it by 100.
For example, suppose the decimal is 0.35.
0.35 × 100 = 35%
So:
0.35 = 35%
Another example:
0.08 × 100 = 8%
Therefore:
0.08 = 8%
A quick way to remember the conversion is to move the decimal point two places to the right and add %.
Decimal to Percentage Examples
| Decimal | Percentage |
|---|---|
| 0.01 | 1% |
| 0.05 | 5% |
| 0.1 | 10% |
| 0.15 | 15% |
| 0.25 | 25% |
| 0.5 | 50% |
| 0.75 | 75% |
| 0.8 | 80% |
| 0.9 | 90% |
| 1 | 100% |
| 1.25 | 125% |
| 1.5 | 150% |
A decimal does not have to be between 0 and 1. For example, 1.5 represents 150%.
How to Convert a Percentage to a Decimal
To convert a percentage into a decimal, divide the percentage by 100.
Percentage to Decimal Formula
Decimal = Percentage ÷ 100
For example:
25% ÷ 100 = 0.25
Therefore:
25% = 0.25
Another example:
75% ÷ 100 = 0.75
So:
75% = 0.75
This is the reverse of converting a decimal to a percentage.
Percentage to Decimal Examples
| Percentage | Decimal |
|---|---|
| 1% | 0.01 |
| 5% | 0.05 |
| 10% | 0.1 |
| 20% | 0.2 |
| 25% | 0.25 |
| 50% | 0.5 |
| 75% | 0.75 |
| 80% | 0.8 |
| 90% | 0.9 |
| 100% | 1 |
| 125% | 1.25 |
| 150% | 1.5 |
Decimal and Percentage: What Is the Difference?
A decimal and a percentage can represent the same value in different forms.
For example:
0.5 = 50%
0.25 = 25%
0.75 = 75%
The value itself has not changed. Only the way it is expressed has changed.
A percentage expresses a value per 100, while a decimal represents the same proportion in decimal form.
For example:
25% = 25/100 = 0.25
Quick Conversion Rule
You can remember both conversions with two simple rules:
Decimal → Percentage
Multiply by 100
Example:
0.42 × 100 = 42%
Percentage → Decimal
Divide by 100
Example:
42% ÷ 100 = 0.42
So the two conversions are opposites:
Decimal × 100 = Percentage
Percentage ÷ 100 = Decimal
Can a Decimal Be Converted to More Than 100%?
Yes.
If the decimal is greater than 1, its percentage will be greater than 100%.
For example:
1.2 × 100 = 120%
Therefore:
1.2 = 120%
Similarly:
2 × 100 = 200%
So:
2 = 200%
This simply means the decimal represents more than one whole.
