You can use this converter to copy and paste values as well, after pasting a value, just click/touch one of the text boxes or select a unit to convert the value.
Pressure unitThe pressure unit, in physics, refers to the force acting vertically on the surface of an object. The unit is Pascal (abbreviated as Pa and the letter is "Pa"). (Strictly speaking, the pressure unit should be Newton N. The pressure unit is Pascal, and it is customary to call pressure as pressure in life).
In China, we generally describe the pressure of gas in kilograms (instead of kilograms). The unit is "kg·f/cm2". One kilogram of pressure means one kilogram of force acts on one square centimeter.

Explanation of pressure unitsThe unit of pressure 1 Pascal (Pa N/m2) is equal to 1 Newton per square meter.
1 bar is equal to 100,000 Pa, which is slightly less than the average atmospheric pressure at sea level on the earth.
1 kilogram per square centimeter (kg/cm2) is a pressure measurement, equal to 1 kilogram force per square centimeter, also known as industrial atmospheric pressure.
1 inch of mercury (in Hg @ 0°C) at 0 degrees Celsius is defined as the pressure produced by a 1 inch of mercury at 0°C and standard acceleration of gravity.
1 pound per square inch (psi) is the pressure produced by applying a force of 1 pound to an area of 1 square inch.
One pound per square foot (psf) is the pressure that a pound of force is applied to a square foot area.
1 mm of water column at 4 degrees Celsius (mm H2O @ 4°C) is defined as the pressure produced by a 1 mm height of water column at 4°C and standard acceleration of gravity.
1 inch of water column (in H2O @ 4°C) at 4 degrees Celsius is defined as the pressure produced by a 1 inch of water column at 4°C and standard acceleration of gravity.
Atmospheric pressure, also known as atmospheric pressure, is the pressure in the earth's atmosphere.
