Can anyone tell me what 40cmHg would be?Thanks all!(as opposed to mmHg?)Will a 40cmHg(max reading limit) give me the vacuum reading ability I would need for the manual's vacuum reading of say 290mmHg?Thanks again!

I'm not sure what you are asking. However, 40cmHg converts to 400mmHg. (10mm = 1cm)

Hopefully that helps

Yep-Thanks AZ-that's what I wanted to know alright!
