Air pressure can be stated in different ways.
kpa is kilopascals, the metric system
psi is pounds per square inch in the standard system
1 bar is equal to the air pressure at sea level
1 kpa= about 7 psi
15 psi = about 1 bar

The measure of the force with which air molecules are pushing on the Earth's surface?
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
How do isobars measure air pressure?
Isobars are not measured. An isobar describes a part of a thermodynamic process during which the pressure doesn't change. It is also used as a term in graph tables where it describes the behavior of a material at a constant pressure.
What does atmospheric pressure measure?
The force of colliding particles
Air pressure is measured in which of the following units?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1,013 millibars. Pressure is also measured in pascals, which is the pressure of 1 newton over 1 square meter. (A newton is the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. 'atmosphere' itself is a unit , abbreviated as atm. 1atm=1.013 x 105. In the English system, pressure is measured in pounds per square inch. A pound per square inch is equal to about 6,890 pascal.
