I have to chane the barometric pressure in my area to ATM. We have to look at the U.S. Weather map that gives the barometric pressure. I live in an area that has shows 1016 for barometric pressure.

First is 1016 in millibars or what and secondly how do I convert that to atm so I can apply it to the gas law?

Please help-I'm really confused-my teacher just assigned this with no other directions

Is ATM a credit card or does it stand for atmospheres. I went to google, typed in 1 millibar and obtained this conversion factor. You can use this factor or type in your own and convert.
