What tools in used to measure atmosphere pressure.? What unit is atmospheric pressure measured in.?

The tools used to measure atmospheric pressure are barometers. Atmospheric pressure is measured in units of millibars (mb) or inches of mercury (inHg).

Tools Used to Measure Atmospheric Pressure:

- Barometer: A device that measures atmospheric pressure by balancing it against the weight of a column of mercury or another liquid.
- Aneroid barometer: A device that measures atmospheric pressure by detecting the expansion or contraction of a flexible bellows or diaphragm.
- Digital barometer: An electronic device that converts atmospheric pressure into a digital reading.
- Altimeter: A device that measures altitude by measuring atmospheric pressure.

Unit of Atmospheric Pressure:

Atmospheric pressure is typically measured in millibars (mb) or inches of mercury (inHg).

- 1 millibar (mb) = 0.02953 inches of mercury (inHg)
- 1 inch of mercury (inHg) = 33.86 millibars (mb)
