Mathematical Formula & Step-by-Step Derivation

SI Standard Math
General Formula:
Volumetric Weight (kg) = (Length(cm) × Width(cm) × Height(cm) × Qty) / Divisor
Live Calculation With Your Input Values:
11. Volumetric Weight Calculation
Formula: Volumetric Weight (kg) = (Length(cm) × Width(cm) × Height(cm) × Qty) / Divisor
Substituted: (50 cm × 40 cm × 30 cm) / 5000
Step Result: Volumetric Weight = 12 kg (26.46 lb)

Total volume = 0.06 CBM. Divisor used: 5000.

22. Chargeable Weight Determination
Formula: Chargeable Weight = MAX(Actual Weight, Volumetric Weight)
Substituted: MAX(10 kg actual, 12 kg dimensional)
Step Result: Chargeable Weight = 12 kg (26.46 lb)

Volumetric weight exceeds actual weight (cargo is low-density/bulky). Freight charges will be billed on volumetric weight.

Volumetric Weight Formulas & Courier Divisors
Metric Standard (cm & kg):Volumetric Weight (kg) = (Length cm × Width cm × Height cm) ÷ Divisor
Imperial Standard (inches & lbs):Volumetric Weight (lbs) = (Length in × Width in × Height in) ÷ 139
Chargeable Weight = MAX(Actual Scale Weight, Volumetric Weight)
Worked Example: Express Air Parcel Comparison

A carton measures 60 cm Long × 50 cm Wide × 40 cm High with an actual scale weight of 10.0 kg (courier divisor 5,000):

1. Volume = 60 × 50 × 40 = 120,000 cm³ = 0.120 CBM

2. Volumetric Weight = 120,000 ÷ 5,000 = 24.0 kg

3. Actual Scale Weight = 10.0 kg

4. Billable Chargeable Weight = 24.0 kg (carrier bills on 24 kg due to large volume)

Common Use Cases

Cost-Saving Shipping Tips:

  • Minimize Void Space: Shaving just 2 cm off each carton dimension can save 15%–20% on volumetric shipping fees for high-volume exports.
  • Calculate Cargo Volume First: Use our CBM Calculator to check total consignment cubic meters and verify whether sea freight (LCL) is more economical than air courier.
  • Full Container Planning: For shipments exceeding 15 CBM, explore our Container CBM Calculator.

How to Calculate Volumetric (Dimensional) Weight

Volumetric Weight (also known as dimensional weight or DIM weight) is a commercial billing method used by air carriers, express couriers (DHL, FedEx, UPS), and freight forwarders.

Because cargo aircraft and transport vans have limited cubic hold space, lightweight, bulky boxes consume disproportionate volume relative to their weight. Freight carriers calculate dimensional weight from package dimensions and bill on whichever figure is higher: Actual Scale Weight or Volumetric Weight.

  1. Measure package Length, Width, and Height in centimeters (cm).
  2. Multiply dimensions to determine total volume in cubic centimeters (cm³).
  3. Divide total cubic centimeters by the carrier's DIM divisor factor (standardly 5,000 for express couriers or 6,000 for IATA air cargo).
  4. Compare volumetric weight against actual gross scale weight. The larger value is the billable Chargeable Weight.

Frequently Asked Questions

What is volumetric weight?
Volumetric weight (dimensional weight) is a calculation reflecting the density of a package. Courier and air carriers compare volumetric weight to actual scale weight and bill on the greater value (chargeable weight).
How do you calculate volumetric weight?
Multiply package Length (cm) × Width (cm) × Height (cm) and divide the result by the carrier's volumetric divisor (standardly 5,000 for express couriers or 6,000 for air cargo).
Why do courier companies use dimensional weight?
Cargo aircraft and trucks reach their physical cubic capacity before reaching their maximum gross weight capacity. Charging for dimensional weight ensures carriers cover fuel and space costs for light, bulky parcels.
What is the difference between 5,000 and 6,000 divisor?
A divisor of 5,000 means 1 cubic meter (1 CBM) equals 200 kg of volumetric weight (standard for DHL, FedEx, UPS). A divisor of 6,000 means 1 CBM equals approximately 166.67 kg (standard for IATA commercial air freight).
What is chargeable weight?
Chargeable weight is the exact weight figure used to determine your invoice freight rate. It is always the larger number between actual gross weight and volumetric weight.
How do I calculate volumetric weight in inches and pounds?
Multiply Length (in) × Width (in) × Height (in) and divide by 139 for international air express (or 166 for domestic freight). The result is volumetric weight in pounds (lbs).
