Enter the length, width, and height of the backpack into the calculator to determine the backpack capacity.

Backpack Capacity Formula

The following formula is used to calculate the backpack capacity.

BC = (L * W * H) / 1000


  • BC is the backpack capacity (liters)
  • L is the length of the backpack (cm)
  • W is the width of the backpack (cm)
  • H is the height of the backpack (cm)

To calculate the backpack capacity, multiply the length, width, and height of the backpack. Then, divide the result by 1000 to convert the volume from cubic centimeters to liters. This will give you the total volume of space available in the backpack for storing items.

What is a Backpack Capacity?

Backpack capacity refers to the volume of space available in a backpack, measured in liters or cubic inches, that can be used to store items. It determines how much gear, clothing, food, and other essentials a backpack can hold. The right capacity for a backpack depends on the length of the trip, the type of activities planned, and the individual’s personal packing habits.
