You don't need to do anything to put it in inches other than take the "mm" out. If you input your tire size in inches your output will be in inches. If you input your tire size in mm, your output will be in mm.
What I wanted to imply was that inches and mm could be done at the same time not one or the other by using separate output boxes
I noticed that Mike B. did his tire size in inches so I wanted to supply equal reference of measurement standards
1 inch = 25.4 mm

Rearranging the equation to get spur is also a useful tool, especially for oval racers. You see it a lot in the pan car threads: people share what tire diameter works best, what spur works well, and a range of target roll out, but never which pinions work with that combination to get into that range!
When you go to a track or get a new car and have a known wheel diameter, known spur, and a known target roll out, you can plug in the constants and get your target spur without having to guess. That especially helps newbs get into the right range their first time out.
Rollout x Spur / Pi (3.14159) / Tire Diameter (mm) = Pinion
Hi so formula's go:
1. Pi X pinion X Tire Diameter / spur = Rollout
2. Rollout x Spur / Pi (3.14159) / Tire Diameter (mm) = Pinion
3. ? = Spur
4. ? = Tire Diameter
Any math geeks out there to do the final two formula's for the other two variable outputs 3 and 4?
1. Pi X pinion X Tire Diameter / spur = Rollout
2. Rollout x Spur / Pi (3.14159) / Tire Diameter (mm) = Pinion
3. ? = Spur
4. ? = Tire Diameter

Thanks
Can someone mathematically inclined help me with these final two equations so I can finish the Rollout companion for those who want alternative outputs for spur, pinion and Tire Diameter

Thank you
you mean?:
3. Pi X pinion X Tire Diameter / rollout = Spur
4. (Rollout X spur) /(Pi X pinion) = Tire Diameter
BTW I did not check your math...
