Worked dimensional-weight example
A 12 × 10 × 8 inch parcel has a planning dimensional weight of 6.91 lb using the 139 in³/lb divisor. Compare that figure with the scale weight, then apply the carrier's rounding and billable-service rules.
Before using the quote
- Confirm the exact service and destination zone.
- Measure the packed outside dimensions, including bulges.
- Check whether the account uses a different divisor or rounding rule.
