DIMENSIONAL-WEIGHT CALCULATIONS
Dimensional Divisor
A dimensional divisor is the denominator used to convert package volume into dimensional weight. The calculation is length × width × height ÷ divisor, with units and rounding defined by the service.
DIMENSIONAL DIVISOR IN PRACTICE
- Confirm the ruleRead units, divisor and rating basis.
- Calculate consistentlyUse external packed dimensions.
- Compare rating inputsCheck dimensional and actual weights.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Same volume. Two hypothetical divisors.
A 6,000 cm³ package gives 1.2 kg at an illustrative divisor of 5,000 and 1.5 kg at 4,000, before rounding. If actual weight is higher than both, that may govern under a greater-of rating rule. These numbers illustrate arithmetic, not a carrier offer.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.

A LITTLE MORE CONTEXT
Questions about Dimensional Divisor
Does a larger divisor increase raw dimensional weight?
No. For identical volume it decreases the raw quotient.
Does dimensional weight always control billing?
No. Actual weight and other service rules can matter.
Are inside carton dimensions sufficient?
Use the service’s required external packed measurements.
