Static head is: The internal energy of a fluid due to the pressure exerted on the containing vessel. Static head remains the same regardless of volume. For each meter you raise the container, the water pressure is amplified by 9.804139432 kpa (kilopascals) At sea level, 1 meter head of water is approximately 10kpa, (atmospheric pressure is 100 kpa.)

They are Bar, PSI, Meter, Kpa & N/m2
0.001 MPa in one kPa
120 kP
1 bar = 100 kPa (kilopascals)
6.9 kPa = 1 psi
44 psi = 303.37 kPa
180 kPa = 26.11 psi
One bar = 100 kPa
101.3 kPa = 1 ATM
Water column head is expressed either as the height of the column ... 6 meters here ... or else as the pressure at the bottom ... 58.842 kPa here. 'Kg' can't be a unit of water column head, and the diameter of the column is irrelevant.
2,500 kPa = 362.6 psi (rounded)
