Converison of pressure or stress  units

Definition: pressure = force per area; p = F/A; F = force, A = area, p = pressure

The SI unit of the pressure is the pascal with the formula sign Pa.
1 Pascal is equal to the pressure of 1 newton per square meter. 1 Pa = 1 N / m2 ≡ 1 kg / m · s2.
The standard atmospheric pressure is 101,325 pascal = 1,013.25 hPa = 101.325 kPa
= 760 mmHg = 29.92 inHg = 14.7 lb/in2.
Good to know: 1 Pa = 1 N/m294 dBSPL and 1 bar = 105 Pa

Fill in the appropriate line the known pressure value
