Convert any decimal into a percentage — values below 1, above 1 and negatives — with the working shown.
To convert a decimal to a percent, multiply it by 100 and add the percent sign. For example, 0.625 × 100 = 62.5%, so 0.625 is 62.5%. A quick shortcut is to move the decimal point two places to the right. This calculator shows the exact result and the steps.
Enter a decimal such as 0.625, 1.5 or -0.2.
Type a decimal number — something small like 0.05, a value above one like 1.5, or a negative like -0.2. Leading-point notation such as .75 and thousands separators like 1,000 are accepted. Press Convert to see the percentage, a note on whether it is below, equal to or above 100%, and the working. Use Copy result to reuse the answer.
Multiply the decimal by 100 and write a percent sign after it. Because our number system is base 10, multiplying by 100 simply shifts every digit two places, which is the same as moving the decimal point two places to the right.
× 100move the point two places right→ 50% 0.25 → 25% 0.75 → 75%→ 1% 1 → 100% 1.5 → 150%
A percentage is a fraction out of 100. The decimal 0.5 means five tenths, which is the same as fifty hundredths, or 50/100. Writing that as a percent gives 50%. Multiplying by 100 converts "per one" into "per hundred", which is what the percent sign stands for.

A decimal greater than 1 becomes a percentage greater than 100%. For example, 1.2 = 120%, 1.5 = 150% and 2 = 200%. A percentage above 100% simply means the value is larger than the whole or reference amount — a price that grew to 1.5 times its start is at 150% of the original.
A negative decimal produces a negative percentage: -0.1 = -10%, -0.25 = -25% and -1.5 = -150%. Negative percentages often represent a decrease, a loss, or a value below a reference point, such as a -10% change in a share price.
Turning decimals into percentages is everywhere: discounts and sale prices, tax and interest rates, test scores and grades, statistics and survey results, financial returns and profit margins, data analysis, and tracking growth or decline. Any time a plain decimal needs to be read as a rate, this conversion makes it clear.
