They's are not asking the same question
If you mean how is elevation on a map measured then it is usally by a different color(usally white means the highest).
The simple answer is zero feet elevation, but first of all, it is almost impossible to tell that you are at the exact sea level that is the average of all the different sea levels caused by all the different tide elevations. That is why GPS and surveying do not much use "mean sea level", anymore. These days "zero elevation" is determined by the strength of the field of gravity as calculated and measured all around the world.
Why is elevation important
Its a starting point where elevations are measured from (The Sea) For instance the Mile High Stadium which is in Denver is 0ne mile above mean sea level or 5280 feet approximately.
Why is elevation important
Elevation can be measured in feet and inches, or metres and centimetres.

Relative to Sea Level.
Elevation is measured with respect to sea level.
Feet and Meters.
Denver, CO is called Mile High City because it measures one mile in elevation from sea level
The elevation of Mt. Everest is 8,846 metres measured from above sea level. This is the tallest mountain above SEA LEAVEL, however the tallest mountain in the world is Mauna Kea in Hawaii with an elevation of 10'200 metres, measured from below sea level. Hope this helped!
the pressure of water measured relative to the atmospheric pressure at the same elevation.
Its elevation has been measured at 15,919' or 4,852 m.
