A foot of mercury (ftHg) is a unit of pressure commonly used in barometry and vacuum measurements. It represents the pressure exerted by a column of mercury one foot tall in a barometer tube. Typically, this measurement is made at standard temperature and gravity conditions. It's a unit particularly relevant in the context of weather instruments and vacuum systems. In meteorology, it's often used to express atmospheric pressure, while in vacuum systems, it's used to gauge the level of vacuum, with higher values indicating lower pressure.
