Decimal to Percentage Conversion
Converting decimals to percentages is one of the simplest mathematical conversions. Since "percent" means "per hundred," you're essentially scaling the decimal by 100.
Formula
Percentage = Decimal x 100
Quick Method
Move the decimal point two places to the right and add the % symbol.
Examples
Example 1: Convert 0.85 to percent
0.85 x 100 = 85%
Example 2: Convert 0.05 to percent
0.05 x 100 = 5%
Example 3: Convert 1.5 to percent
1.5 x 100 = 150%
Common Conversions

Understanding the Relationship
Decimals and percentages represent the same value in different forms. A decimal is parts per one, while a percentage is parts per hundred. This is why we multiply by 100 to convert.
