# What is *pressure*?

**Pressure**is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

## Input

**torr**is a unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere or exactly 101325/760 of a pascal.

## Output

**Pound Per Square Inch**(

*more accurately*:

**Pound-force Per Square Inch**, lbf/in²) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
