why we messure differential pressure in pascle,mmhg,mmwc like different units in different company..

Answer / sbaskar

All are different units of pressure only.We use pascal,mmwc,orkg/cm2 for our convenience only.For instance if the pressure drop is minimum we use mmwc as it can be viewed easily using a watertube manometer instead of a pressure gauge.
