These constants retain their exact values in symbolic calculations. To redefine the value of any of these constants, use the equal sign for definition (:=) as you would to define any variable.

1L, 1M, 1T, 1Q, 1K, 1C, and 1S |
assigned by the selected unit system |
Define custom unit definitions for the base dimensions. |
To redefine system constants, use the equal sign for definition (:=) in your worksheet, as you would to define any variable, or choose Worksheet Options from the Tools menu, and go to the Built-in Variables tab.
| Symbolic Math Constants |
The following constants can only be evaluated using the symbolic equal sign or the Symbolics menu. They cannot be evaluated using the equal sign for evaluation (=).
