• Wheel circumference: 220 cm

Transformation

let C:      circumference
let rpm:    revolutions per minute
let km/h:   kilometer per hour
let m/min:  meter per minute

km/h 2 m/min

v (km/h) = x * 1000m / 60min

km/h 2 u/min

T/min = v * 1000m / (60min * Cm)

example:

let v = 25 km/h
let C = 2.20 m

rpm = 25 * 1000m / (60min * 2.20m)
rpm = 189.394 T/min
