How to Use Pressure Conversion table?
A pressure converter table helps in converting one unit of pressure to other units of pressure quickly and easily. The table given is a pressure conversion table that helps convert pressure units.
To use the chart, locate the desired pressure unit and multiply it by the value in the pressure unit column that corresponds to it.
Example: Convert 2 millibars to kilopascal (kpa)
Solution:
To convert millibars to kilopascals we have to multiply 2 by 0.1, which gives the required value in kpa,
i.e.,
2 millibars = 2 × 0.1
= 0.2 kilopascals.

Pressure Conversion Table
Pressure is defined as the force applied perpendicularly to the surface of an object per unit area over which that force is distributed. In simple words, pressure is the ratio of force to area. It is a scalar quantity and is represented as “p or P.” We have various units to express pressure, and some of these are derived from the ratio of the unit of force to the unit of area. The SI unit of pressure is the Pascal (Pa), and apart from it, we also have different units to measure the pressure that are frequently used, such as pounds per square inch (psi), atmospheric pressure (atm), bar, torr, etc. The formula to calculate pressure when a force of “F” Newton is applied perpendicularly to a surface area “A” is equal to the ratio of “F” to “A.”
p = F / A
where,
“p” is the pressure exerted on the surface by the force F
“F” is the force applied perpendicularly to the surface of an object
“A” is the surface area of an object
The SI unit of pressure is the Pascal, where one Pascal is equal to one newton per square meter.
1 Pascal = 1 N/m2
