Formulas

Explanation

Assume an object (or point) attached to a rotating wheel. The angular velocity of the wheel is defined by \( N \) expressed in \( rpm \). The angular velocity of the wheel can be converted to \( rad.s^{-1} \) thanks to the following formula:

$$ \omega_{ (rad.s^{-1}) } = \frac {2\pi}{60}.N_{(rpm)} $$

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:

$$ v_{(m.s^{-1})} = r \times \omega_{(rad.s^{-1})} = r \times \frac {2 \pi }{60}.N_{(rpm)} $$

and vice-versa:

$$ N_{(rpm)} = \frac {60} { 2 \pi \times r} v_{(m.s^{-1})} $$
