Convert Fraction into Percent

Please enter two values for the fraction, the percentage value will be calculated. If nothing is entered for one of the two values, then this value is filled with a 1.

Examples: 3/5 corresponds to 60 percent. 5/3, on the other hand, corresponds to 166.666... percent.

A fraction in the form numerator divided by denominator is called a common fraction. If the amount in the numerator is smaller than that in the denominator, it is called a proper fraction. The other way around, it is an improper fraction. Negative fractions can also be used, in which case you have to enter a minus in front of one of the two values. If you enter a minus in the numerator and denominator, so both are negative, then -1 is canceled out and the fraction becomes positive again.

This calculator can also work with decimal fractions. To do this, simply fill in the first of the two values. However, you can also easily convert a decimal fraction into percentages without a calculator; all you have to do is multiply it by 100. For example, 0.25 corresponds to a percentage value of 25.
Whether percentages over 100, which result from improper fractions, or negative percentages make sense depends on the context. For example, if you have estimated two half-hour periods for a certain activity and instead need three half-hour periods, i.e. the time is 3/2 of the planned time, then you would have a percentage value of 150. This value is certainly reasonable and possible, which would not apply to negative values in this example. On the other hand, if you have to cover 1500 meters from the start to the finish and you first run 200 meters in the exact opposite direction, then you can certainly see it as having covered -13.333... percent of the distance.
