What deos a barometer measure?
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
A pressure gauge reads57 psi The equivalent pressure in inches of mercury absolute is?
116.1 inches of mercury.
What is the absolute pressure at 20 inches of mercury?

When the height of the mercury in a barometer is 29.92 inches the barometric pressure is?
The standard sea level pressure of Earth's atmosphere - a pressure of 1 Bar or one "atmosphere".
What unit of measurement does an barometer use?
Barometric pressure is usually measured in inches of mercury, millibars (mb), or hectoPascals (hP).
Antique aneroid barometer has a scale of 28 to 31 what units are these?
A meterological type of barometer uses a column of mercury that is supported by atmosperic pressure. The height of this column varies with the atmospheric pressure and was at one time measured off in inches in the range of about 28 to 31 "inches of mercury". The scale now used is Millibars both in aneroid and mercury barometers.
What units are used on an antique Danish barometer with a scale of 24.6 t0 29.6?
Just as a guess, they're probably inches of mercury. Standard air pressure is set at 29.92 inches of mercury.
Why is air pressure measured in inches?
by a barometer
