Chambered...I took my apprenticship from 1958 to 1961 and was a journyman from 1961 on. I learnd in a Europian automotive shop and had to know SAE, Metric and an old English wrench that I can't remember how to spell. We do not need metric in the world I live in...Maybe the doctors and scientists need the meteric system, but not machinist and mechanics.

I understand the difference between CUP and PSI. They just need to settle on one and not keep listing both. Then the next thing I'll need is a chart for calibre & PSI equivelence...

could that old english system be call whitworth?

Yup...A lot of the English cars use whitworth. In particular MGTC,TD and TF...

I've seen a Whitworth cannon before, on Oak Hill at Gettysburg. Does that count?

Doesn't a CUP hold PSI? (Pretty steamy instant.) Laughing

Only reason they keep bringing up cup and psi , is so you can see they think they no sumpthin' you dont ..
As was said there is no way to directly compare the two on a linear scale ..
Very few of us have the equipment to measure either one , tho I do lust after the Oehler system ..
So my take is it was written , ssame reason they write all the other junk , they run outta stuff to write about , and look and say "oh we havent written about this , since last month , time to do it again"
