Q:
Is a barometer required to measure air and atmospheric pressure?
A:
Yes! A barometer is an instrument used to measure air pressure at a specific location, in 'millibars,' a unit of measurement of pressure based on the first ever experiments with air pressure, where it was measured in inches of mercury.
Barometers are used everywhere from ships to airplanes to help figure out the pressure of the air.
