revolutions per minute [rpm] rpm radius [m] radius [m] kilometers per hour [km/h] km/h

Formulas

• Convert rpm to km/h
• Convert km/h to rpm

Explanation

The angular velocity of the wheel (in rpm) can be converted into \( m.s^{-1} \) thanks to the following formula:

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

It becomes easy to convert this linear velocity expressed in \(m.s^{-1} \) into \(km.h^{-1} \) thanks to the following formula:

$$ v_{ (km.h^{-1}) } = \frac {3600}{1000}.v_{(m.s^{-1})} = 3.6 \times v_{(m.s^{-1})}$$

By merging the two previous equations, we can deduce the relationship between revolution per minute [rpm] and kilometers per hour [km/h]:

$$ v_{ (km.h^{-1}) } = \frac {3600}{1000} \times r \times \frac {2 \pi }{60}.N_{(rpm)} = \frac {3}{25}. \pi. r . N_{(rpm)} $$

et vice versa:

$$ N_{(rpm)} = \frac {25} { 3. \pi . r} v_{(km.h^{-1})} $$
