Decimal to Percentage Formula
To express a decimal as a percentage, multiply it by 100. Moving the decimal point two places to the right is a convenient way to visualize the same operation: 0.625 becomes 62.5%, while 1.25 becomes 125%.
Values Above One and Negative Values
A decimal greater than 1 correctly produces a percentage above 100%, because the value represents more than one whole. Negative decimals produce negative percentages and can be useful when expressing declines, losses or values below a reference point.
