Use our Free Pressure Converter| Pressure Unit Conversion Calculator to easily convert pressure units like Pascal (Pa), Bar, PSI, Atmosphere, Torr, mmHg, kPa, mbar, and more
Pressure is perhaps the most significant physical quantity in science, engineering, and everyday use. It determines the amount of force exerted per unit area, and it's utilized everywhere—from forecasting the weather to industrial systems and car mechanics.
Yet, pressure is expressed in varying units according to application or area of use. For example, scientists employ Pascals (Pa), meteorologists utilize millibars (mbar), engineers use PSI (pounds per square inch), while physicists tend to deal with atmospheres (atm) or Torr.
To make all these conversions easier, the SEO Pheonix Pressure Converter gives a simple, precise, and immediate online tool to convert from/to all major pressure units — including Pascal (Pa), Bar, PSI, Atmosphere, mmHg, Torr, and kPa.
Pressure is the force exerted per unit area.
Mathematically:
P= F/A
Where:
P = Pressure
F = Applied force (in Newtons)
A = Area (in square meters)
Following are the most common units of pressure used by the SEO Pheonix Pressure Converter:
Pressure units differ significantly across industries and measurement systems.
For instance:
Weather forecast employs millibars or hectopascals
Tire pressure employs PSI
Physics laboratories employ Pascal or Torr
Engineers use bar or MPa
