# Wheel - Calculate Covered Distance, Circumference, Diameter and Radius

Calculator for the number of revolutions of a wheel at a certain distance, or for the distance, for cars, bicycles and other vehicles. Often, front and rear wheel have different sizes, therefore two wheels can be calculated and compared here. Please enter for one wheel or both wheels distance or revolutions and radius, diameter or circumference. The other values will be calculated.

The units are cm for centimeters, m for meters, km for kilometers, ″ for inches, ′ for feet and mls for miles.

**Distance** is the covered distance. If the two wheels are front and rear wheel, both distances should be equal.

**Revolutions** specifies, how often the wheel turns around at the covered distance.

**Radius** of a wheel is the span between center and edge, **diameter** ist twice the radius, the span from edge to opposite edge.

**Circumference** is the distance a wheel covers at one revolution.
