Pressure Unit Conversion Calculator Applications
This calculator applies when attempting to express a pressure measurement in a number of different units. This can be useful when working with pressure sensors in an electronic circuit, designing mechanical parts, or modeling a physical system.
Units of Pressure
This calculator converts between the following units of pressure:
- Pascal (Pa) = 1 N/m2
- Bar (bar)
- Kilogram per square centimeter (kg/cm2)
- Millimeters of mercury (mm Hg)
- Inches of mercury (in Hg)
- Pound per square inch (lb/in2)
- Pound per square foot (lb/ft2)
- Millimeters of water column at 4 °C (mm H20)
- Inches of water column at 4 °C (mm H20)
- Standard atmosphere (atm)
