The formula for the pressure P = F / S is here associated with a unit converter

The pressure unit is N/m2(newtons per m²)or pascal (Pa).

Meteorologists express pressure in millibars.
    1 mb = 0.10 kPa

    1 Pa = 1 N / m 2 , 1 kPa = 1 x 10 3 Pa

absolute pressure (P abs) is the pressure measured with reference to pressure
zero. The pressure gauge (PG) is a measure of the difference between the
absolute pressure and atmospheric pressure (Patm).

Pabs = PG + Patm

In mécaflux pressures in the ducts are configurable using the
reservoir pressure (absolute pressure).

To enter a pressure tank other than the atmospheric pressure

To enter a pressure tank other than the atmospheric pressure
ambient, uncheck the box atm pressure. and enter your absolute pressure.
Beware the pressures in the reservoirs are absolute pressures (Pabs = PG + Patm).
data powers will update accordingly ...
