Price per unit = Total price ÷ Number of units
Identify the total cost of the item or package
Identify the total number of units in the package
Divide the total price by the number of units
Use the result as the price for one unit
Example: $12 for 4 items = $3 per item
If needed, convert all measurements to the same unit before dividing
Compare price per unit across products to find the better value
