Mean sea level is the average (mean) height of the sea. http://en.wikipedia.org/wiki/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.
above sea level
Yes, mean sea level (MSL) is the average (mean) height of the sea.

The lowest point in Hawaii is in the Pacific Ocean at sea level. what the heck!
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?

No it is not the sea level definitely depends on where you are located like in Florida is considered below sea level and in Colorado they are above sea level
Sea level pressure, sometimes as mean sea level pressure.
It has an elevation ranging from sea level to 520 feet above sea level.
That is really a strange question. Never heard that any part of Germany is below sea level.
