*Harmonic Mean Calculator* is an online statistics tool programmed to calculate Harmonic Mean from the number of observations, divided by the sum of reciprocals of the observations. The harmonic mean is one of the three Pythagorean means, involving in many situations where rates, ratios, geometry, trigonometry etc considered, the harmonic mean provides the truest average

### Definition

**Harmonic Mean** is the reciprocal of the arithmetic mean of the reciprocals. In other words, it is the number of observations, divided by the sum of reciprocals of the observations. This is also is one of several kinds of average and it is appropriate for situations when the average of rates is desired

### Harmonic Mean Formula

The harmonic mean H of the positive real numbers x_{1}, x_{2}, x_{3}, ...x_{n} > 0 can be derived from the formula
