Enter the total weight (lb) and the total number of items into the Item Weight Calculator. The calculator will evaluate the Item Weight. 

Item Weight Formula

The following two example problems outline the steps and information needed to calculate the Item Weight.

IW = TW / I


  • IW is the Item Weight (lb)
  • TW is the total weight (lb) 
  • I is the total number of items 

To calculate the item weight, divide the total weight by the total number of items.

How to Calculate Item Weight?

The following steps outline how to calculate the Item Weight.

  1. First, determine the total weight (lb). 
  2. Next, determine the total number of items. 
  3. Next, gather the formula from above = IW = TW / #I.
  4. Finally, calculate the Item Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total weight (lb) = 300

total number of items = 230

IW = TW / #I = ?
