16 PSI is not equal to 1 ATM, 14.7 is the closest to 1 ATM i know of in PSI.

I have a vacuum in my closet at home

and its not a partial vacuum, its a complete vacuum :c)

I use to have a vacuum in my basement too, but when my daughter went away to college, she took it with her - she needed to have a complete vacuum too, in her apartment.
