In formula:

P=F/A

Where:



P = the pressure being derived



F = the force applied by the weights



A = the effective area of the piston cylinder

1.4 Determine of the pressure

The reference level of the deadweight tester is at the top of the sealing of the pressure connection. If the weight set is

marked with a pressure unit (MPa; bar; psi or kg/cm²) the pressure can be determined by the formula:
