How this calculator works
Speed is converted to m/s. Reaction distance is speed times reaction time; braking distance is speed squared divided by twice the effective deceleration.
Checked example
Example: 60 km/h, 1.5 s reaction and 6 m/s² deceleration gives 25 m reaction plus about 23.15 m braking, or 48.15 m total.
Assumptions and privacy
All calculations run locally in your browser. WheelMela does not save or transmit calculator inputs. Results depend on your inputs and should be treated as planning estimates.
