According to Wikipedia, pressure is the force per unit area applied in a direction perpendicular to the surface of an object. Mathematically, this can be expressed as.

or

In a gravity field, the force is created by the weight of an object, which can be calculated as

, where g is the acceleration due to gravity, measured in meters per square second.

Therefore, the formula for pressure in a gravity field can be expressed as

By default, this calculator uses g = 9.80665, which is the value for Earth's gravity field. The area used in the calculation is the average surface area of a pair of shoes.

The results are displayed in metric units, specifically in Pascals, as well as in other units of pressure that are available in the Pressure Units Converter.
