Convert radians [rad] to meters [m] and vice-versa

Introduction

You can't actually convert radians to meters. Radian is a measure of angle, while meters is a unit of distance. There is an homogeneity issue between the two quantities.

However, there are many mechanical systems that transform rotary motion into linear motion. In this page, we'll considere this kind of system. Please read the explanation for more information.

How to convert radians to meters

However, there are many mechanical systems that transform linear motion into rotary motion. The most obvious system is the wheel: the rotation of the wheel moves the vehicle forward and vice versa. In this case, the formula governing such a system and allowing to transform a displacement (of the vehicle) given in meters into a rotation (of the wheels) of an angle expressed in radians is given by:

$$ L = r * \alpha $$

and vice-versa:

$$ \alpha=\frac{L}{r} $$
