2. Select T > [Store].
3. Use the dialog that appears to input one letter from A to Z and then press O.
• This stores the atomic weight value to the alpha variable of the letter you input.
• For details about alpha variables, see
Fundamental Physical Constants
The Database app maintains the values of the physical constants shown in the table below and displays them
in a list grouped by category. You can edit the physical constant values and store them to an alpha variable for
use in other applications.
Note
• The values and names of the physical constants included in the Database app are based on 2022
CODATA.
