I think you are confusing force (newtons) with pressure (pascals), which
is force per unit area.
Things like air pressure are measured in pascals or, more traditionally,
in bars (1 bar = 100 kilopascals), and sometimes (even though rarely
nowadays) in atmospheres (1 atm = 101325 Pa).

Ah, thank you. I never really learned what a "bar" was. So one bar is
approximately one atmosphere? That sounds about useful.

See the other thread about Andrew's heating system, it's also useful that 1
bar ~= 10 metres of water for quick estimations.

Or 1 bar ~= 34 feet of water. (In real money) ;-)
