Why is sea level used to measure the height of a place?
The height of a landform on Earth is DEFINED as its height above sea level since sea level is the closest thing on Earth to a constant or standard starting point. Sea level itself changes with the tides and wind and weather, so we use what is called "mean sea level" which is an average of measured levels at a given place over an extended time.

How we can calculate height of a place from sea level?
The height of a place from sea level can be calculated using a device called an altimeter, which measures the atmospheric pressure. By comparing the atmospheric pressure at the location with the standard atmospheric pressure at sea level, the height above sea level can be determined. GPS receivers can also provide accurate altitude information by using satellite signals.
