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.

20-ft

Count of twenty-foot containers.

40-ft

Count of forty-foot containers.

Convert a mixed fleet of twenty- and forty-foot containers into total twenty-foot equivalent units (TEU) and forty-foot equivalents (FEU), where one FEU equals two TEU. 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]

TEU

Total capacity in twenty-foot equivalent units (one 40-ft box counts as two).

FEU

Total capacity in forty-foot equivalent units.

• 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.

• CBM Cubic Meters from Cartons

  Convert centimetre carton dimensions into cubic metres per carton and the shipment total for a carton count.

• Container Per Diem Charges Computation

  Multiply chargeable detention or demurrage days by the daily per-diem rate and apply an optional total charge cap, where a cap of zero means uncapped.

• Cost per Unit Shipped Allocation

  Allocate a shipment's supplied freight and fee total evenly across its sellable units; this does not weight allocation by mass, volume, or value.
