How to Calculate Dimensional Weight
Measuring overlapping edges
Measure to the nearest inch (centimeter). Use the greatest measurement in each direction
Calculate the volume using the diameter as the length and the width. The box has the same dimensional weight as the cylinder.
Measuring irregular shapes
Place the package in a corner in the position it will be loaded. Measure by holding a straight edge at the right angles to the wall.
Examples of calculation
A shipment weighs 10 lbs. It measures 14 in by 16 in x 16 in. (14 x 16 x 16) / 166 = 21.59. Rounded up to 22 lbs.
A shipment weighs 10 kilos. It measures 45 cm by 45 cm x 50 cm. (45 x 45 x 50) / 6000 = 16.8. Rounded up to 17 kg.
The formula for calculating the dimensional weight for all commodities is 166 cubic inches per pound (6000 cubic centimeters per kilogram or 366 cubic inches per kilogram). Multiply the length by the width bythe height to obtain the cubic inches (cm).
- To obtain the dimensional weight in kilograms, divide the cubic inch result by 366.
- To obtain the dimensional weight in pounds, divide the cubic inch result by 166.
- To obtain the dimensional weight in kilograms, divide the cubic centimeter result by 6000.
If the dimensional weight is greater than the actual weight, use it to calculate the transportation charges.
