3.7. Scientific constants
Calculator for Chemists can be used as common scientific calculator, but it also includes a molecular weight calculator and tables with various physical and chemical constants. The symbol of an element is figured as a constant whose value is the elements molecular mass. You can enter pi for the Pi number constant or select the Pi value from the INSERT menu.
Select physical constants from the INSERT menu and click the constant which you want to insert into expressions.
