PARCEL DIMENSIONS & RATING
Dimensional Factor
A DIM factor is the conversion value used in a dimensional-weight calculation. When used as a divisor, it converts package volume into a pricing weight under the carrier’s specified units and rules.
DIMENSIONAL FACTOR IN PRACTICE
- Measure the packageUse external packed dimensions.
- Apply the factorDivide volume using compatible units.
- Determine rating weightCompare with actual weight as required.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
Illustration: 6,000 ÷ 5,000 = 1.2.
A hypothetical centimetre/kilogram rule uses a divisor of 5,000. A 30 × 20 × 10 cm package has volume 6,000 cm³ and dimensional weight 1.2 kg before applicable rounding. This invented rule illustrates the calculation; it does not quote a current carrier contract.
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 Factor
Is the factor always 5,000?
No. The example uses a hypothetical value.
Does the factor alone give shipping price?
No. It helps establish a rating weight.
Can the same number be used with any units?
No. Units must match the carrier’s rule.
