Calculate in
Feet:
1. L x W x H = Total
Cubic Foot
2. Divide Weight by Total
Cubic Foot = Freight Density - ranges from 50 (Class 50) to
Less-than-1 (Class
500)
Example Calculation:
1. L=12' x W=3' x H= 5' equals to 80
Cubic Inch
2. Divide the cargo-example: 985
Lbs by 80 Cubic Inch = 11.19 Freight
Density in Pounds per Cubic Foot
3.
Using the calculated density, in this
example between 10.50 and 11.99 to get an
estimated Freight Class
92.5
Calculate in
Inch:
1. L x W x H
= Cubic Inch
2. Divide by 1728 = Cubic
Foot
3. Divide
Weight by Cubic Foot = Freight Density - ranges from 50 (Class 50) to
Less than 1 (Class
500)
Example Calculation:
1. L=125" x W=40"
x H= 60" equals to 300,000 Cubic Inch
2. Divide
300,000 by 1728 = 173.61 Cubic Foot
3.
Divide the cargo-example: 1,500 Lbs by 173.61 Cubic Foot =
8.64 Freight Density
in Pounds per Cubic Foot
4. Using the calculated
density, in this example between 8.00 and 8.99 to get an
estimated Freight Class
110
Remarks:
The
above "Classification Density
Guidelines" are based on weight and
dimensions and the final Freight Class needs to be
determined by the Carrier
before creating the Bill of Lading (BOL)
with exact commodity descriptions listed.
