Technical How to measure your bolt pattern

Oh wow !!!!!!! The science is so over whelming that it has resorted to pocket protector with scale ruler mentality.

I didn't learn this till I was 29... Now I measure with confidence!

 

This is what I do, center to center and add 1/4"

 

To find mm I just x by 25.4

 

I can measure with the tape. And I can convert inches to mm.
I just saw this at Carlisle and thought it would be really handy for $10.
Now I can give this to someone who can't read a tape well and say don't bring that axle/drum/wheel home if it doesn't line up right here on this number!!!
Saved me more than $10 in wrong parts.
