There is a point in Cornwall, in the UK, where there is a hatch in a building and underneath is a mark from which mean sea level for the entire world is calculated. It is in Newlyn, I think.
Answer
MSL is the average between high and low tides, and is a datum point used to desribe the height of tides, although the actual measurement is quite complex. The Newlyn mentioned above is the datum point for the UK, not the world. Other countries have their own datum point.

Where is the standard mean sea level located?
The standard mean sea level is located at the midpoint between the high and low tide marks along a particular coast. It serves as a reference point for measuring elevation and is defined as the average level of the sea's surface over a specified period of time.
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.
What is the level of the ocean's surface called?
Yes, mean sea level (MSL) is the average (mean) height of the sea.
How do you calculate sea level?
Mean sea level is the average (mean) height of the sea. http://en.wikipedia.org/wiki/Sea_level
Elevation at sea level is what?
The elevation at sea level is defined as 0 feet or 0 meters. This serves as a reference point for measuring elevations above or below sea level on land.
Is the land elevation at sea level 100 feet?
No, sea level is defined as an average level for the surface of one or more of Earth's oceans. Land elevations can vary around sea level, but sea level itself is determined by the average height of the ocean's surface.
What is the sea level for New Mexico?
Mean sea level is 5,692 feet.
Mean sea level of delhi?
1043 ft above sea level
Which term is defined as the atmospheric pressure at sea level at zero degrees celsius?
Standard conditions, or standard temperature and pressure (STP) is the atmospheric pressure at sea level with temperature at zero degrees Celsius (273.15 Kelvin).
What is the difference between sea level and elevation?
Sea level ~ average (mean) height of the sea, with a reference to a suitable reference point. Elevation ~ height of a geographic location above mean sea level.
What is the air pressure at sea level called?
Sea level pressure, sometimes as mean sea level pressure.
How high is sea level?
Well, sea level is the standard by wich other things are measured, so zero is the answer. Sea level is sea level. Compared to what?
