 One can find these two ways of measuring the turning circle used in auto specifications, for example, a van might be listed as having a turning circle (in meters) of 12.1(C)/12.4(W).A notable exception in this description is of vehicles that are capable of spinning around their central axis, such as certain lawnmowers and wheelchairs as they do not follow a circular path as they turn.In this case the vehicle is referred to as a "zero turning radius" vehicle.
