How to use Percent to Decimal
Type a percentage without the % sign, such as 45 or 7.5. The decimal appears straight away.
How to convert a percent to a decimal
Remove the percent sign and divide by 100, which is the same as moving the decimal point two places to the left. 45% becomes 0.45, 7.5% becomes 0.075 and 150% becomes 1.5.
When you need the decimal form
Formulas use the decimal form of a rate. A 5% interest rate is entered as 0.05, a 20% discount as 0.2 and 3.5% growth as 0.035. Typing 5 instead of 0.05 makes the result 100 times too large.
The formula
decimal = percent ÷ 100
Examples
- 45%
0.45
