Three carton sizes in one shipment
A: 60 × 40 × 30 cm × 10; B: 50 × 35 × 25 cm × 6; C: 40 × 30 × 20 cm × 8
Calculation: 0.7200 + 0.2625 + 0.1920
Expected: 1.1745 m³; 24 cartons
Load these inputs →Express divisor 5000
50 × 40 × 30 cm; actual 7 kg
Calculation: 60,000 ÷ 5000
Expected: 12 kg before service rounding
Load these inputs →Air-freight divisor 6000
50 × 40 × 30 cm; actual 7 kg
Calculation: 60,000 ÷ 6000
Expected: 10 kg before service rounding
Load these inputs →U.S. rectangular parcel comparison
20 × 15 × 10 in; actual 12 lb
Calculation: ceil(3000 ÷ 139) = 22; ceil(3000 ÷ 166) = 19
Expected: 22 lb FedEx, UPS Daily and USPS Ground Advantage; 19 lb UPS Retail, before other rating rules
Load these inputs →Four equal pieces
60 × 40 × 35 cm; 10 kg each; four pieces; divisor 5000
Calculation: max(4 × 10, 4 × 84,000 ÷ 5000)
Expected: 67.2 kg before service rounding
Load these inputs →Two Euro-pallet layer orientations
120 × 80 cm pallet; 40 × 30 × 25 cm carton; 14.4 cm deck; 180 cm overall height
Calculation: max(3 × 2, 4 × 2) × floor((180 − 14.4) ÷ 25)
Expected: 8 per layer × 6 layers = 48 cartons
Load these inputs →Count full layers, including pallet height
40 × 30 × 25 cm cartons on 120 × 80 cm pallet; overall height 180 cm
Calculation: 8 × floor((180 − 14.4) ÷ 25)
Expected: 48 cartons; loaded height 164.4 cm
Load these inputs →Length plus girth in inches
48 × 20 × 16 in
Calculation: 48 + 2 × 20 + 2 × 16
Expected: 120 in
Load these inputs →USPS rounded volume threshold
12.1 × 12 × 12 in; actual 8 lb
Calculation: 13 × 12 × 12 = 1872; ceil(1872 / 139) = 14
Expected: 14 lb USPS Ground Advantage base comparison
Load these inputs →The same cartons in a 40 ft preset
60 × 40 × 35 cm; 12 kg each; 1203 × 235 × 239 cm interior
Calculation: 20 × 5 × 6
Expected: 600 cartons; 7200 kg; 50.4 m³ of cartons
Load these inputs →High cube crosses one more layer threshold
60 × 40 × 40 cm; 12 kg each; 1203 × 235 × 269 cm interior
Calculation: 20 × 5 × 6
Expected: 600 cartons versus 500 in the standard 40 ft preset
Load these inputs →Payload reduces the geometric count
60 × 40 × 35 cm; 120 kg each; 20 ft preset; 28,300 kg payload
Calculation: min(270, floor(28300/120))
Expected: 235 cartons; 28200 kg; about 59.67% volume utilization
Load these inputs →Why these examples matter
A calculator can look correct while hiding a unit-conversion, orientation, or divisor error. Publishing fixtures makes the expected behavior auditable. When calculator logic changes, these examples provide a stable reference point for manual and automated checks.
