A 10-inch cube under the 139 dimensional divisor profile

Compare actual and dimensional parcel weight with explicit US FedEx, UPS Daily, UPS Retail or custom profiles. Apply the selected rounding and divisor to estimate billable weight, not shipping prices.

Illustrative manual assumptions in USD unless units are stated. This is a reproducible example, not a marketplace settlement or carrier quote.

Inputs

Package length: 10 in
Package width: 10 in
Package height: 10 in
Actual scale weight: 3 lb
Measurement units: Inches and pounds
US package rule profile: FedEx US package · divisor 139
Custom divisor: 139 in³/lb

Calculation

All dimensions are whole inches: volume = 10 × 10 × 10 = 1,000 in³.
Raw dimensional weight = 1,000 ÷ 139 = 7.194244… lb.
Round dimensional weight upward to 8 lb. Actual weight rounds to 3 lb.
Billable basis = max(8, 3) = 8 lb for this supported package profile.

Result: 8 lb billable weight.

Assumptions and limits

Profile 0 is the modeled FedEx US package profile; units 0 means inches/pounds. The output is a weight basis, not a rate quote. Surcharges, minimum charges, special services and negotiated rules can differ.

Selected US package profiles only; current guide/account agreement governs. Service exceptions, contract divisors, oversize and unsupported packages require separate review. Handling thresholds may change the minimum weight; see result warnings. No rates, surcharges or delivery quote.
