## How to Convert a Percentage to a Decimal Value

Often a percent value will need to be converted to decimal form to allow it to be used in other equations. The decimal form will not have the symbol.

Since percent literally means “per 100” converting to a decimal form is as simple as dividing the percentage by 100 and removing the % symbol. See the formula below:

d = p ÷ 100

One way to divide by 100 is to simply move the decimal point to the left 2 places. For example:

27.5 ÷ 100 = .275

To convert a decimal back to a percentage use our decimal to percent calculator.

Example: convert 48.5% to a decimal

d = p ÷ 100
d = 48.5 ÷ 100
d = .485
