Explanation: hg is the chemical symbol for mercury. It seems the sentence is stating the air pressure in the room. Since I'm not a scientist myself and have never really interested myself in air pressure, I don't know how that would be said in layman's terms. What units are commonly used to measure atmospheric pressures? Atmospheres??
