How to Change Number to Percentage: A Quick Guide

Converting Whole Numbers to Percentages

To convert a whole number to a percentage, simply multiply it by 100 and add the percent sign (%). This transforms the number into its percentage equivalent. For example:

• 5 becomes 5 * 100 = 500%
• 25 becomes 25 * 100 = 2500%

While simple, manual calculation can be tedious. Use our calculator for instant conversions.

Converting Decimals to Percentages

Converting a decimal to a percentage involves a similar process. Multiply the decimal by 100 and add the percent sign. This is particularly useful when dealing with ratios or proportions:

• 0.75 becomes 0.75 * 100 = 75%
• 0.05 becomes 0.05 * 100 = 5%
• 0.36 becomes 0.36 * 100 = 36%

Our tool allows you to quickly calculate the percentage of a number without manual multiplication.

Converting Fractions to Percentages

To convert a fraction to a percentage, first divide the numerator by the denominator to get a decimal. Then, multiply the decimal by 100 and add the percent sign:

• 1/2 becomes (1 ÷ 2) * 100 = 50%
• 3/4 becomes (3 ÷ 4) * 100 = 75%
• 1/5 becomes (1 ÷ 5) * 100 = 20%

Percentage Change Calculations

Understanding how to convert numbers to percentages is also essential when calculating percentage change, whether it's an increase or decrease. To calculate percentage change, you'll need two numbers: the initial value and the final value. The formula is:

Percentage Change = [(Final Value - Initial Value) / Initial Value] * 100

If the result is positive, it indicates a percentage increase; if it's negative, it indicates a percentage decrease.

For instance, if a stock's initial price was $50 and its final price is $60, the percentage change would be: [(60 - 50) / 50] * 100 = 20%. Thus, there's a 20% increase in the stock price.

Our calculator not only helps with basic conversions but also simplifies these percentage change calculations, allowing you to quickly calculate percentage increase or decrease.
