About this calculator
The reciprocal, or multiplicative inverse, of a number x is the value 1/x that, when multiplied by x, yields exactly 1; every nonzero number has one, and this calculator returns it both as a decimal and as a percentage.
Reciprocals appear constantly in everyday math and science: converting a pace like minutes per mile into a speed like miles per minute is a reciprocal operation, dividing fractions works by multiplying by the reciprocal of the divisor, and in electronics the reciprocal relationship governs how resistances combine in parallel circuits. Algebra students use the reciprocal concept to solve equations involving division, and anyone converting between rate and time uses it routinely.
Enter any nonzero number and this calculator instantly returns its reciprocal, showing exactly what value you need to multiply it by to reach 1.
