Likewise, who invented the mercury barometer and what is it used to measure? Evangelista Torricelli
Beside above, how is a barometer used?
The barometer works by balancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales. If the weight of mercury is less than the atmospheric pressure, the mercury level in the glass tube rises (high pressure).
At what barometric pressure does it rain?
If the reading is under 29.80 (100914.4 Pa or 1009.144 mb): Rising or steady pressure indicates clearing and cooler weather. Slowly falling pressure indicates rain. Rapidly falling pressure indicates a storm is coming.
