# 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

**Bar**is a metric unit of pressure, but not part of the SI units, defined as exactly equal to 100,000 Pa (100 kPa).

## Output

**Pascal**is the SI derived unit of pressure defined as one newton per square meter (1 N/m²).
