How it is calculated
A decimal becomes a percentage when you multiply it by 100; the decimal point moves two places to the right. Percent means “per hundred”, so 1 is 100 %, 0.5 is 50 % and 0.01 is 1 %.
Both directions
Decimal → percent: multiply by 100 and add the percent sign. Percent → decimal: divide by 100, so the point moves two places to the left. The calculator also shows the value in permille (times 1000) and as a simplified fraction, found with the greatest common divisor.
Examples
0.375 · 100 = 37.5 %. As a fraction that is 375/1000, reduced by the GCD 125 to 3/8. In reverse, 12.5 % divided by 100 gives 0.125, which is 1/8. Values above 1 work too: 1.5 equals 150 %. Negative numbers keep their sign: −0.25 is −25 %.
- 0.07 is 7 %, but 0.7 is 70 % – watch the zero after the point.
- Percent and percentage points differ: from 10 % to 12 % is 2 percentage points but a 20 % increase.
