dynamic meter

The standard unit of dynamic height, defined as 10 m2 s−2; it is related to the geopotential φ, the geometric height z in meters, and the geopotential height Z in geopotential meters by

where g is the acceleration of gravity in meters per second squared. (Some sources prefer to give the constants 10 and 9. 8 the units of meters per second squared so that the units of φ and Z would be the same as those of the geometric height. )

The dynamic meter is about 2% longer than the geometric meter and the geopotential meter.
