I'm old school what does .6-.7mm = in thousands? I'd need to go buy a different gage if I used that. Thanks Bill.

No older then I :>)
.6mm = .0236
.7mm = .0276

For future reference, Bandito, just remember there are 25.4mm in one inch.

So, to convert from MM to inch, you divide it by 25.4. 0.6mm / 25.4 = 0.23622
And the reverse for the opposite!

I run my plug (CR7HIX) at .026, works great!

Huh? ok thanks all............

metric is a euro thing I'm american.

 

[The_Aleman]

Metric isn't just a Euro thing. It's an international standard, and only a couple of African countries and the US cling to the inch system.

Anyway, it all comes down to math. All I did was try to show you an easy to to convert MM to inch.

I'll put that formula in my tool box for future use, thanks.
