Pressure

The pressure corresponds to the force which is applied to the surface area. Here, the force is relative to the area under pressure, thus, is divided by the surface area. The absolute pressure is assumed to be 0 bar. This is (in theory) also the lowest attainable atmospheric pressure. At sea-level the atmospheric pressure is exactly 1013 hPa. All measuring instruments and values in technology show the relative pressure, the basis of which is the atmospheric pressure.

F p =        A F = p · A        F A =        p

1 bar = 10 N/cm²

1 Pascal = 1 N/m²

1 bar = 100.000 Pascal
