Pressure Conversion

Pressure Unit Explanations

• A Pascal (Pa N/m²) is a unit of pressure equivalent to one newton per square meter.
• A Bar is equal to 100000 Pa and is slightly less than the average atmospheric pressure on Earth at sea level.
• Kilogram-force per square centimeter (kgf/cm²) is a pressure measure equal to one kilogram-force per square centimeter, another name for this unit is technical atmosphere.
• Inches of Mercury column at 0 degrees Celsius (in Hg @ 0°C) is defined as the pressure exerted by a column of Mercury 1 inch in height, at 0°C, at the standard acceleration of gravity.
• Pound per square inch (psi) is the result from a force of one pound-force applied to an area of one square inch.
• Pound per square foot (psf) is the result from a force of one pound-force applied to an area of one square foot.
• Millimeters of water column at 4 degrees Celsius (mm H₂O @ 4°C) is defined as the pressure exerted by a column of water 1 mm in height, at 4°C, at the standard acceleration of gravity.
• Inches of water column at 4 degrees Celsius (in H₂O @ 4°C) is defined as the pressure exerted by a column of water 1 inch in height, at 4°C, at the standard acceleration of gravity.
• Atmospheric pressure also called barometric pressure, is the pressure within the atmosphere of Earth.
