How to convert a decimal to a percent
A decimal is a value measured out of 1. A percent is the same kind of value measured out of 100 instead — per hundred, which is what the word "percent" means. Moving between the two is one step: multiply by 100, which shifts the decimal point two places to the right.
- Multiply the decimal by 100:
0.75× 100. - Write the result with a percent sign:
75%.
Worked examples
A one-digit decimal
0.2 shifts to 20%. One digit after the point becomes two digits before the percent sign, padded with a zero.
A three-digit decimal
0.125 shifts to 12.5%. The point only ever moves two places — the third digit stays after the point, on the percent side too.
A decimal larger than 1
1.5 shifts to 150%. Percents above 100% are ordinary — they just mean more than the whole.

Where people get it wrong
The decimal point moves the wrong way more often than the wrong number of places. 0.06 correctly becomes 6%, not 0.0006%. Multiplying by 100 always moves the point right — toward a bigger-looking number, not a smaller one.

Frequently asked questions
How do you convert a decimal to a percent?
Multiply by 100, which shifts the decimal point two places to the right. That single move is the entire method — no reduction step, no intermediate fraction.
Which direction does the decimal point move?
Right, and by two places. Moving it left instead divides by 100, giving a far smaller number than the correct percent.
Can a decimal convert to a percent over 100%?
Yes — any decimal larger than 1 does. 1.5 converts to 150%, the same way 0.5 converts to 50%; the method never changes.
Does this work for a repeating decimal?
Yes, the same way — multiplying by 100 doesn't change whether the digits repeat, only where the decimal point sits. A repeating decimal converts to a repeating percent.
Why is 100 the number used, specifically?
Percent means per hundred. A decimal is already a value out of 1, so multiplying by 100 rescales it to a value out of 100 — the same amount, on a different scale, not a new calculation.
