Michael,
Now I know how much air to put in my soccer balls (footballs to you) at .7
to .9 BAR. Equates to 10 to 13 psi. But I still don't know what type of
measurement a BAR represents. Obviously not the same as an atmosphere.
It's been over 30 years since I went to college so I've had a few senior
moments since then. The air in my MG tires didn't need filling while I
visited Canada on my honeymoon in 1972 so I don't recall what air pressure
measurement you use. Please don't tell me that Pascal had anything to do
with it.
