Explanation:
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
The 3 main factors that affect barometric (air) pressure are: Temperature. Altitude or Elevation. Moisture ow water vapour.
In SI base units: 1 N/m2, 1 kg/(m·s2), or 1 J/m3
Derivations from other quantities: p = F / A
Dimension: M L−1 T−2
SI unit: Pascal
