The unit torr is related to the barometric height as:
- 1 torr = 1 cm of Hg
- 1 torr = 0.76 cm of Hg
- 1 torr = 1 mm of Hg
- 1 torr = 1 m of Hg
The atmospheric pressure at earth surface is P1 and inside mine is P2. They are related as:
- P1 = P2
- P1 > P2
- P1 < P2
- P2 = 0

- to measure atmospheric pressure
- for weather forecasting
- as an altimeter to measure heights
- all of the above
