FAQ
Why do we divide a percentage by 100?
Percent literally means 'per hundred', so dividing by 100 converts the fraction of 100 into a base-1 decimal.
Can I convert percentages greater than 100%?
Yes. Values above 100% simply produce decimals above 1, such as 250% becoming 2.5.
How do I use the decimal in a spreadsheet formula?
Insert the decimal directly—for example, multiply a price by 0.075 to apply a 7.5% tax rate.
Is the decimal result unitless?
Yes. The decimal represents the same proportion as the original percentage without any attached unit.
