Using a calculator to convert units of pressure is straightforward. Pressure is a measure of how force acts on a surface and is calculated using the formula: 

P = F/A, 

where 

P represents pressure, 

F is the normal force, and 

A is the area.

Since pressure is essentially force divided by area, many pressure units directly relate to this concept. For example, pounds per square inch (psi) and the SI standard unit, Pascal (Pa), both express force per unit area. In fact, one Pascal is equal to one Newton per square meter.

To convert between different pressure units, you can use a conversion factor. This makes the conversion process a simple multiplication problem, following the formula: 

S * C = E, 

where 

S is the starting value, 

C is the conversion factor, and 

E is the end result.
