Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Actual weight (kg)

Scale weight of the shipment in kilograms.

Length (cm)

One carton side in centimetres; side order does not affect volume.

Width (cm)

A second carton side in centimetres.

Height (cm)

The remaining carton side in centimetres.

Volumetric divisor (cm³/kg)

Cubic-centimetres-per-kilogram divisor from the applicable carrier tariff; defaults to 5000.

Compare actual and volumetric weight before carrier-specific dimension, weight, or billing rounding; an exact tie uses actual weight. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Volumetric weight (kg)

Unrounded volumetric weight in kilograms.

Chargeable weight (kg)

Greater of actual and volumetric weight before tariff rounding.

Billing basis

Which basis the chargeable weight came from.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Dim Divisor US-EU Comparison Lookup

  Compare volumetric weight for the same carton under a US express-style divisor (default 5000 cm3/kg) and an EU road-style divisor (default 3000 cm3/kg), both overridable from your tariffs.

• Additional Handling Fee Trigger Checker

  Check a rectangular parcel against configurable longest-side, second-longest-side, actual-weight, and length-plus-girth thresholds; packaging and service-specific rules are outside this numeric screen.

• Dimensional Weight Divisor Calculator

  Compute volumetric weight as L x W x H in centimetres divided by your tariff's dimensional divisor (default 5000 cm3/kg for air freight).
