How it works
Percent to decimal
percent ÷ 100 = decimalRemove the % sign, then move the decimal point two places to the left, adding zeros in front if needed: 7.5% → 0.075.
Percents over 100 give decimals over 1: 250% = 2.5.
This is the step behind every “percent of” calculation: 7.5% of 200 = 0.075 × 200 = 15.
