Examples of the WaterSteamPro Custom Units functions
used in Microsoft Excel
Set dimensions in needed form: Used formula:
Pressure (to MPa): 1 =wcuSETCU(1;1000000;0)
Temperature (to C): 1 =wcuSETCU(2;1;273,15)
Volume (m3/kg): 1 =wcuSETCU(4;1;0)
Internal energy ,enthalpy (MJ/kg): 1 =wcuSETCU(6;1000000;0)
Entropy (kJ/kg*K): 1 =wcuSETCU(5;1000;0)
