FAQ
Is 1 bar the same as 1 atmosphere?
Close, but no. One standard atmosphere is 1.01325 bar, so the two differ by about 1.3 %.
Is a pressure in bar gauge or absolute?
The unit does not say. Gauge pressure reads above the surrounding atmosphere and absolute pressure reads above vacuum. At sea level, add about 1.013 bar to a gauge reading to get absolute pressure.
