Mean sea level is the average (mean) height of the sea. http://en.wikipedia.org/wiki/Sea_level
Something on land can be measured as below sea level when its elevation is lower than the average level of the world's oceans. This can be determined using a reference point, such as sea level, to calculate the vertical distance below it. Topographic maps and GPS technology are commonly used to measure elevations above and below sea level.
above 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.
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?
Yes, mean sea level (MSL) is the average (mean) height of the sea.
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
14.7 psi = sea level. 15.2 psi = 1671 ft below sea level
It has an elevation ranging from sea level to 520 feet above sea level.
Sea level pressure, sometimes as mean sea level pressure.
That is really a strange question. Never heard that any part of Germany is below sea level.
No, altitude and sea level are not the same thing. Altitude is the distance of a location above sea level, while sea level is a specific level used as a reference point for measuring elevations. Sea level represents the average level of the ocean's surface.
