How to calculate volumetric weight?

If you are invoiced by weight
Transport prices are based on a minimal density of 12,4 lbs per cubic foot (may vary according to your contract). The transportation cost is calculated on the highest weight, whether it’s the real weight or the volumetric weight.

In order to find the volumetric weight of your parcel, you must multiply the 3 dimensions of your parcel and divide the result by a precise factor (inches or cm).

In inches

(Length x Width x Height) divided by 1728 = Volume of your parcel in cubic feet.

Ex. : (24″ x 12″ x 12″) /1728 = 2.0 cu. ft.

2.0 cu. ft. X 12,4 lb = 24,8 lbs

In centimeters

(Length x Width x Height) divided by 28316 = Volume of your parcel in cubic feet.

Ex. : (61 cm X 30,5 cm X 30,5 cm) /28316 = 2.0 cu. ft.

2.0 cu. ft. X 12,4 lb = 24.8 lbs

If you are invoiced by parcel
If you have a “by the piece” rate agreement, volumetric weight does not apply the same way. According to your Nationex agreement, a surcharge can apply if your parcel is over 4,0 ft cubic foot for example. The standard class sizes are:

Standard Class volume

Class A. 0 to 4,0 cu. ft.  = No Charge
Class B. 4,01 to 8,0 cu. ft.
Class C. 8,01 to 12,0 cu. ft.
Class D 12,01 to 16 cu. ft.
Note. Parcels weighing 65 lbs and over are also considered Class B and are subject to a surcharge.

In inches

(Length x Width x Height) divided by 1728 = Volume of your parcel in cubic feet.

Ex. : (36″ x 18″ x 18″) / 1728 = 6,75 cu. ft.

6,75 cu. ft. = Class B

In centimeters

(Length x Width x Height) divided by 28316 = Volume of your parcel in cubic feet.

Ex. : (100 cm X 60 cm X 30 cm) /28316 = 6,35 cu. ft.

6,35 cu. ft. = Class B
