Explanation

Pressure is typically measured in units of force per unit area.

In the Imperial system, pressure is commonly measured in Pounds per Square Inch (PSI).

This is a widely used unit of pressure in engineering, physics, and many other fields.

Other common units of pressure include:

• Atmospheres (atm)
• Bars
• Pascals (Pa)
• Torr
