How to Calculate Freight Density (Step by Step):

Following steps can be used to manually calculate the Freight Density of the shipment. If shipment consists of multiple packages, following steps need to be repeated for each piece.

Step-1: Measurement of Dimensions:

Measure the length, width and height of the freight pallet using a simple measuring tape.

Step-2: Measurement of Weight:

Measure weight of the shipment using a weighing balance.

Step-3: Volume Calculation:

Multiply the 3 above mentioned dimensions of the freight pallet to find the volume of the shipment by using the following formula:


$$Volume = Length \times Width \times Height$$

Step-4: Density Calculation:

Compute the density of the shipment by dividing the already measured weight of the pallet with the calculated volume as per the following formula:


$$Density = \dfrac{Weight}{Volume}$$
