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.

Length (cm)

Longest carton side in centimetres.

Width (cm)

Middle carton side in centimetres.

Height (cm)

Shortest carton side in centimetres.

Divisor (cm³/kg)

Volumetric divisor in cm3 per kg from your carrier tariff (e.g. 5000 air, 3000 road).

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). 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

Volumetric weight in kilograms.

• 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.

• Fuel Surcharge Percent Add-On Calculator

  Add a percentage-based fuel (or emission) surcharge from your carrier tariff to a base freight charge.

• Billable Weight (Max of Actual vs Dim) Calculator

  Compare actual and volumetric weight before carrier-specific dimension, weight, or billing rounding; an exact tie uses actual weight.
