Formula for Units Per Carton
The formula used for calculating units per carton is very simple:
Units Per Carton = Total Number of Units / Total Number of Cartons
This gives you the average number of individual items packed per carton.
Example:
Let’s say:
- Number of Units = 600
- Number of Cartons = 30
Units Per Carton = 600 / 30 = 20
So, on average, each carton contains 20 units.
