This is why cubic inches are converted into liters which is a standard unit and can be universally accepted.
You know, the volume of the backpack tells what the backpack can hold.
On the other side, the dimensions of the backpacks tell about the size of the things that can be in them.
What You Can Put In a 20 Liter Backpack?

For example, you can keep your notebooks and other study material if you are going for tuition classes or you can keep your laptop in it so that you can work at the cafeteria you visit every evening.
Now, as you know not every backpack has the same number of pockets and compartments.
This is why manufacturers have to measure the capacity/volume of each compartment including the pockets and then sum them together, to get the precise volume of the backpack.
To calculate the volume of the backpack, some manufacturers pour water into the backpack.
The volume of the water required to fill the backpack is the volume of the backpack.
The volume of Water Required = Volume of Backpack
The volume is basically measured in cubic inches but because cubic inches can not be universally accepted, this is why it is necessary to convert the cubic inches into Litres.
