    How does the rest of the world measure PSI?

    How does the rest of the world measure pounds per square inch?

    When I went to school we used PSI but today you use atmospheres where 1 atm = 14.7 PSI (approx) There is also mm of Hg and Pascals. If I recall correctly 760 mm of Hg (mercury), (which is also called Torr) is the pressure at sea level.  I could look it up but I forgot Pascals I just remember it is just over 1000 but being basically lazy I always liked atmospheres.

    I believe that most of the world uses kilopascals (kPa) instead of pounds per square inch when talking about pressure.  One kPa is equal to 1,000 newtons per square meter.  One newton is 1 kg-meter per second squared.  One kPa is also approximately 6.895 kPa.  So a standard car tire pressurized to 30psi would have a pressure of 206.85 kPa.
