Pressure
Conversion
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.
Pressure Units Explained
- Pascal (Pa): The SI unit of pressure. One pascal is equal to one newton per square meter. It is a very small unit, so kilopascals (kPa) are often used.
- Bar: A metric unit of pressure, but not part of the SI. 1 bar is exactly equal to 100,000 Pa. It is slightly less than the average atmospheric pressure on Earth at sea level.
- PSI (Pound-force per square inch): Commonly used in the US for tire pressure and industrial applications.
- Atmosphere (atm): An international reference pressure defined as 101,325 Pa. It approximates the average atmospheric pressure at sea level.
- Torr: A unit of pressure based on an absolute scale, defined as 1/760 of a standard atmosphere.
[!TIP]
Fun Fact: The pressure at the deepest point in the ocean (Mariana Trench) is over 1,000 times standard atmospheric pressure. That’s like having an elephant stand on every square inch of your body!
