0.987atm equals 1bar. Actually to be more accurate it's 0.98692atm = 1bar, close enough though maybe I should change it to the exact amount. Yeah I should.
Yeah usually you'll see it represented the other way, 1atm = 1.01325bar. So for those who don't want to look these guys up, they are all scientists who came up with equations pertaining to gases, pressures, etc and a bar is a unit of measurement for pressure.
So it reads: Charles, Boyle, and Avogadro walk into a bar...
Which to me is hilarious and works on so many levels but maybe I'm an idiot?
