Answer 1

Answer:

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.

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

Answer 2

Answer

Pressure is defined to be the amount of force exerted per area.

Types of pressure: Absolute pressure, gauge pressure, differential pressure, Vacuum Pressure Sensor

• Absolute pressure. The clearest reference pressure is the pressure zero, which exists in the air-free space of the universe.
• Atmospheric pressure.
• Differential pressure.
• Overpressure (gauge pressure)
