How to convert decimal to percent?

Now, let’s look at how to convert decimal numbers into percentages? In fact, it is very simple, usually there are two ways:

Method 1: Regardless of whether it is a whole number or decimal, just multiply it by 100. Please remember to add the percentage sign after the conversion is complete. For example, 0.5 = 0.5 * 100% = 50%.

Method 2: Move 2 decimal points to the right. There are three situations:

1If there are 2 or more decimals after the decimal point, then just move the decimal point two digits to the right.
2There is only 1 decimal place after the decimal point, such as 2.3, then the decimal point moves 2 digits to the right, and 0 must be added after the data, such as: 2.3 -> 23 -> 230%
3When there is no decimal point, that is to say, the number to be converted is a whole number, then just add two zeros directly afterwards, such as: 5 -> 500%

As with the first method, remember to add the percentage symbol after the conversion, which is the correct result.

Solved examples using decimal to percent calculator

Convert more than two-digit decimal to percent

For example, convert 0.375 to percent

Method 1, multiply 100

0.375 = 0.375 * 100% = 37.5%

Method 2, move 2 decimal points to the right.

0.375 -> 3.75 -> 37.5 -> 37.5%

So, 0.375 = 37.5%

Convert two-digit decimal to percent

For example, convert 0.25 to percent

Method 1, multiply 100

0.25 = 0.25 * 100% = 25%

Method 2, move 2 decimal points to the right.

0.25 -> 2.5 -> 25 -> 25%

So, 0.25 = 25%

Convert one-digit decimal to percent

For example, convert 0.3 to percent

Method 1, multiply 100

0.3 = 0.3 * 100% = 30%

Method 2, move 1 decimal points to the right and add zero after the data.

0.3 -> 3 -> 30 -> 30%

So, 0.3 = 30%

Convert whole number to percent

For example, convert 12 to percent

Method 1, multiply 100

12 = 12 * 100% = 120%

Method 2, Add two zeros directly after the number.

12 -> 1200 -> 1200%

So, 12 = 1200%
