WebHowever, because water is so much lighter than mercury, the tube would have to be somewhere in the neighborhood of 33 feet high to exert 14.5 pounds per square inch. Mercury only needs a tube about 30” high for the same pressure. But you already knew that since the standard atmospheric pressure is 29.92 in/hg at sea level! WebAccording to NOAA (National Oceanic and Atmospheric Administration), the average barometric pressure is 29.92 inches of mercury. Typically, pressure instruments use 30 inches of mercury or an equivalent unit of measure as the standard. Absolute Pressure Instruments, Mechanical Pressure Gauges, Digital Gauges and Transducers
