When should I use the harmonic mean instead of the average?

Use it when averaging rates like speed or price-per-unit, where the arithmetic mean would overstate the true average.

Harmonic Mean Calculator

The harmonic mean is used when averaging rates or ratios, such as speeds over equal distances, giving more weight to smaller values than the arithmetic mean.
