How to calculate
Convert travel distance into nominal wheel revolutions using a rolling diameter.
Wheel revolutions =
distance*1000000/(pi*diameter)Nominal circumference =
pi*diameter/1000 mRevolutions per kilometre =
1000000/(pi*diameter)Worked example
- Rolling diameter (mm): 650
- Travel distance (km): 1
- Wheel revolutions: 489.71
- Nominal circumference: 2.04 m
- Revolutions per kilometre: 489.71
Assumptions and limits
The ideal no-slip circle ignores load deformation, wear, pressure and slip. A labelled tire size is not a measured rolling diameter.

Understanding the result
Convert travel distance into nominal wheel revolutions using a rolling diameter. Divide travel distance by circumference using consistent units. One kilometre contains one million millimetres.
When this tool is useful
