Convert radians per second [rad/s] to meters per second [m/s] and vice-versa

Online converter

Convert any value from / to radians per second [rad/s] to meters per second [m/s], angular velocity to linear velocity. Fill one of the following fields, values will be converted and updated automatically.

radians per second [rad/s]
radius [m]
radius [m]
meters per second [m/s]



Assume an object (or point) attached to a rotating wheel. The angular velocity of the wheel is defined by \( \omega \) expressed in \( rad.s^{-1} \). This also means that the wheel rotates from \( \omega \) radians during one second. During that same second, the attached object (or point) travels a distance of \(r \times \omega \). It implies that the speed of the object is also equal to \(r \times \omega \). The conversion can be done thanks to the following formula:

$$ v=r\omega $$

and vice-versa:

$$ \omega=\frac{v}{r} $$

If the previous demonstration did not convince you. You can extend the formula that convert angle to distance :

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

by replacing
