Enter the total cargo volume (ft^3) and the total cargo weight (lbs) into the Stowage Factor Calculator. The calculator will evaluate the Stowage Factor. 

Stowage Factor Formula

The following two example problems outline the steps and information needed to calculate the Stowage Factor.

SF = V *2240 / CW


  • SF is the Stowage Factor (ft^3 / ton)
  • V is the total cargo volume (ft^3) 
  • CW is the total cargo weight (lbs) 

To calculate a stowage factor, multiply the cargo volume by 2240, then divide by the total cargo weight.

How to Calculate Stowage Factor?

The following steps outline how to calculate the Stowage Factor.

  1. First, determine the total cargo volume (ft^3). 
  2. Next, determine the total cargo weight (lbs). 
  3. Next, gather the formula from above = SF = V *2240 / CW.
  4. Finally, calculate the Stowage Factor.
  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 cargo volume (ft^3) = 300

total cargo weight (lbs) = 5000

SF = V *2240 / CW = ?
