Dumbest question ever asked!

Worst thing about this "liters" horse$hiate is that it is not "convertible" You can't convert liters into CID it is not accurate enough.

I once got into a hell of an argument back in the "parts counterman" days when metrics was first showing up in cars. Some woman comes in and starts bla bla bla about how the metric system is "so standardized."

I told her "that is not always true. There are different bolt threads commin in different countries just like anything else."

"NO NO NO!!! A metric bolt is a metric bolt!!" She raged

OK lady. Drive your Jap car to France and then try to buy a bolt to fit it, the French like to use different thread pitches.

And plumbing................there IS NO real standardization with plumbing fittings, and worst, "some" are so close to 'Murican 1/8 pipe for stuff like oil pressure that you are "tempted" to just "strip it right in"
