How to Convert a Percent to a Decimal

Often a percent value needs to be converted to decimal form to allow it to be used in other equations. Once the percent is converted to decimal form, it does not have the % symbol.

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

There are two simple ways to convert a percent to decimal. The first is to use a formula, and the second is to shift the decimal point.

Method One: Using the Percent to Decimal Formula

To convert from percent to decimal, use the following formula:

decimal = percent / 100

Thus, the decimal value is equal to the percent value divided by 100.

To convert a decimal back to a percent you can multiply the value by 100%.

Method Two: Shift the Decimal Point

The second method to convert a percent to decimal is to simply move the decimal point to the left two places and remove the percent symbol. For example:

27.5% = 0.275

Notice that in the example above, the decimal point was shifted to the left two places.
