The vertical dimension of an object.

In air operations, the height above ground level at which the aircraft is flying at the moment of ordnance release. Bombing heights are classified as follows: very low: below 100 feet; low: from 100 to 2,000 feet; medium: from 2,000 to 10,000 feet; high: from 10,000 to 50,000 feet; very high: 50,000 feet and above.

The vertical distance between the waterline and the highest point of a ship’s structure.

The vertical distance from the earth's surface or target to the point of burst.

An atmospheric pressure expressed in terms of altitude which corresponds to that pressure in the standard atmosphere.

A level determined by vertical measurement from mean sea level, maintained during a flight or portion thereof.

The height above the intended impact point at which the parachute or parachutes are fully deployed.

An atmospheric density expressed in terms of the altitude which corresponds with that density in the standard atmosphere.

Conventionally, an altitude above 10,000 metres (33,000 feet).
