Set local ground level to 700 ft, and record the inches of mercury.
1 answer:
The main way in which an altimeter measures the altitude of an object is by calculating the location's air pressure.
<h3>What is an Altimeter?</h3>This refers to the instrument that is used to measure the altitude of an object when it is at a fixed level.
Hence, we can see that an altimeter should NOT be confused with a barometer, because although they both measure pressure, a barometer calculates the change in air pressure and elevation based on available weather.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.
