That said, if it is like my Bell speedometer you take the tire's diameter, convert it to millimeters then multiply times 3.1416

This will help with that conversion:

Inches to Millimeters - in to mm conversion

I then use a GPS to verify.
I am working numbers up & down to try and get a feel for the direction and when I get close I will match the speed with my GPS.

I just assume someone on here could save me some time.
