Calculate Decimal into Percentage Now! →The Basics: Decimals and Percentages
Before diving into the conversion, let's define what decimals and percentages are.
- Decimal: A number expressed in the base-10 system, containing a whole number part and a fractional part separated by a decimal point (e.g., 0.75, 1.25).
- Percentage: A way of expressing a number as a fraction of 100, denoted by the percent sign "%" (e.g., 75%, 125%). It's about finding percentage of a number.
Converting Decimal to Percentage: The Manual Method
The basic formula for converting a decimal into a percentage is simple:
Percentage = Decimal × 100%
Here's how it works:
- Multiply by 100: Multiply the decimal number by 100. This shifts the decimal point two places to the right.
- Add the % Sign: Affix the percentage symbol "%" to the result.
Examples:
- 0.5 becomes 0.5 × 100% = 50%
- 0.85 becomes 0.85 × 100% = 85%
- 1.20 becomes 1.20 x 100% = 120%

Real-World Applications
Understanding the conversion from a decimal into percentage isn't just academic; it's useful in many practical situations:
- Retail: Calculating discounts (e.g., a 0.25 discount on a product is a 25% discount).
- Finance: Understanding interest rates (e.g., an interest rate of 0.05 is 5%).
- Statistics: Interpreting data (e.g., a response rate of 0.60 is a 60% response rate).
- Body Fat: Use our body fat percentage calculator.
Understanding Increase and Decrease
Percentages are particularly useful for expressing increase or decrease. For example, if a value increases from 0.5 to 0.7, the percentage increase can be calculated as:
- Convert both values to percentages: 0.5 = 50%, 0.7 = 70%
- Calculate the difference: 70% - 50% = 20%
- The value increased by 20%. For a more accurate calculation, use our tool for calculating percentage increase.
