Decimal to Percent Converter

This tool takes a decimal and multiplies it by 100 to give the same value written as a percent. It needs one number field, and the answer is exact.

What this tool does

You type a decimal into the single number field and the tool multiplies it by 100, which is the whole conversion. Nothing else is asked for.

It works out the answer only when you press Convert, and the result then appears in a card below the button. Copy writes that result and its unit to the clipboard, and Clear resets the form so you can start again.

Decimal to percent formula

percent = decimal x 100

Multiplying by 100 restates the decimal on a scale of one hundred. In the table below, 0.25 is shown as 25% and 0.125 as 12.5%, so a value such as 0.5 comes out as 50% and 1 comes out as 100%.

A decimal above 1 simply gives a percent above 100: the table lists 1.5 as 150%.
