Question

how is pressure measured?
pressure is measured as force per inch.
pressure is measured as force per unit area.
pressure is measured as force per gram.
pressure is measured as force divided by mass.

Explanation:

Pressure is a physical quantity defined as the force exerted per unit area. The SI unit of pressure is the pascal (Pa), which is equal to one newton per square - meter ($1\ Pa = 1\ N/m^{2}$). Force per inch is a measure related to linear force density, force per gram and force divided by mass are related to acceleration concepts (from $F = ma$).

Answer:

Pressure is measured as force per unit area.
