Depending on your persuasion, the "g" means gage or gauge.  Which, in turn,
means that the scale is zeroed at atmospheric pressure at sea level at a
particular temperature (most likely 0 degrees C., the triple point of H2O,
but I do not remember for sure and I am too lazy to look it up).  The other
scale, psia, indicates absolute pressure which is zero at a complete vacuum.
