# Log Settings: Calculated Values

The "Calculated Values" (CV) tab is where users can create calculations using logged items, factors, and rolling calculations. Calculation types include addition, subtraction, multiplication, and division. As many calculations can be made as necessary, as long as the units between each item are compatible.

Existing calculations can be used in future calculations. *Ex: Total Group A is the addition of three calculated values (Logged Item A1, Logged Item A2, etc.)*

All calculated values can be chosen to show up in the View All Logs page, which can be exported as a .xlsx file.

This is what the CV tab looks like with a few calculations set up:

**💡****Tip: **Units of the same measurement type can be chosen for output/input units in the drop-down seen below.

*Although the calculation uses pounds, the user can choose the output units to be mg, tons, etc.*
