I wonder why vacuum is sometimes measured in range from 0 to -1 bar. Is it because of it's measured relatively to normal atmospheric pressure?
I guess that normally, vacuum shoud be in range of 0 to 1 bar or something?
Can you help me understaning what terms "underpressure" and "overpressure" really means?
Thanks
