For example for the measurements of the atmospheric pressures and in many other technical purposes.

Yes, absolute pressure is the pressure measured with respect to a vacuum, while static pressure is the pressure exerted by a fluid due to its motion or position. While they are related, they are not the same as static pressure does not take into account the atmospheric pressure.
Well, to measure absolute pressure, you must know the speed, distance, and volume in terms of time. I use v/d +3vt=11/78s+ the atmospheric pressure
Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure includes atmospheric pressure as a reference point. To accurately gauge pressure in a system, one can use a gauge that measures gauge pressure and then add the atmospheric pressure to get the absolute pressure. This allows for a more precise measurement of the pressure within the system.
Gauge pressure is smaller than absolute pressure.
To convert between absolute pressure in kPa to gauge pressure in mm Hg, you can use the conversion factor of 1 kPa = 7.5 mm Hg. Therefore, if the required absolute pressure is 20 kPa, the corresponding gauge pressure would be 20 kPa * 7.5 mm Hg/kPa = 150 mm Hg.
The Abbreviation for Manifold Absolute pressure is MAP.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}
No, gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
The absolute pressure can be calculated by adding the atmospheric pressure to the gauge pressure. If the atmospheric pressure is 101.3 kPa, then the absolute pressure of the gas would be 206 kPa + 101.3 kPa = 307.3 kPa.
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
To calculate the gauge pressure of a system, subtract the atmospheric pressure from the absolute pressure of the system. Gauge pressure Absolute pressure - Atmospheric pressure.
