You are measuring the weight of the atmosphere in a vertical column above your head from the Earth's surface to the atmosphere's outer reaches. Air may seem like it weighs nothing, but it is composed of a huge quantity of gas particles whizzing around in empty space. Collectively the weight of these gas particles exert a measurable value. The average weight of the atmosphere is conveniently referred to as 1 atmosphere which is equal to 101,325 pascals or 101.325 kilopascals. These are the most common units of measurement for atmospheric pressure.

What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
How can you determine the mass volume and density of a textbook a container of milk and an air balloon?
You need to measure the mass using appropriate equipment. You can measure the volume of a textbook and a container of milk by measuring its linear dimensions and calculating the volume. It is not at all easy to measure the volume of an air balloon. You cannot use displacement of a fluid (water) because when submerged, the balloon would be experiencing water pressure and so would occupy a smaller volume. You cannot measure it by allowing the air to escape and measure that volume of air because that air will no longer be experiencing the pressure exerted by the material (rubber?) of the balloon. I have no answer to this part. Once you have the mass and volume, the density is merely mass/volume.
What unit of measuring would you use to measure a pencil?
You would measure it in centimeters.
How would you measure the length of a hallway?
With a ruler, or a measuring tape.
What are you measuring when you measure in meter cubes?
M3 volume
What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
What suffix means tool to measure pressure?
-meter is the suffix used in names of measuring instruments. Specifically, a barometer is used to measure air pressure.
What did people use the barometer for?
To measure pressure in the air. Meteorologists use them (weather people) a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
What are you measuring when you are measuring air pressure?
When you are measuring air pressure, you are measuring the force that the air is exerting outwards, on whatever you are using to compress it (since materials resist being compressed). For example, measuring the air pressure in a balloon is measuring the amount of force that the air is pushing against the material of the balloon. This is usually expresed in Pounds per Square Inch (PSI).

What do scientists use o measure air pressure?
A barometer to measure air pressure.
Which devise is used to measure air pressure?
A barometer is used to measure air pressure.
What are instrument use in measuring?
A barometer measures air pressure; a hygrometermeasures humidity, or the moisture content of the air; and an air sampler (or high volume air sampler) is used to measure the purity or pollution level of the air.
