Shipping & Container Converters
TEU capacity, chargeable weight, load planning, revenue tons, voyage time, and bunker density — answer-first for forwarders and vessel ops.
How factors are sourced, how the library is updated, and how IEEE 754 rounding is treated are documented on the About page.
Container TEU / FEU
Convert 20′, 40′, 40′ HC, and 45′ containers to TEU/FEU and typical internal CBM and payload.
Chargeable Weight
Compare actual vs volumetric weight for ocean (CBM×1000) and air (CBM×167) freight rules.
Container Load Planner
Estimate how many cartons fit in a container by volume and payload weight limits.
Revenue / Freight Ton
Compare weight tons and measurement tons (CBM) and take the greater for ocean quoting.
Voyage Time
Estimate steaming time from nautical miles and vessel speed in knots.
Bunker Fuel Volume ↔ Weight
Convert HFO, VLSFO, and MGO between metric tonnes and cubic meters using planning densities.
Shipping converter FAQs
How these freight tools fit into booking and operations.
What shipping converters are included?
TEU/FEU and container capacity, chargeable/volumetric weight (ocean and air rules), carton load vs payload, revenue/freight tons, voyage time from NM and knots, and bunker fuel mt↔m³.
Are container CBM and payload figures exact?
They use common dry-van planning specs. Actual internal volume and payload vary by manufacturer and tare weight — confirm against the equipment CSC plate for booking.
What chargeable-weight rules are used?
Ocean planning uses 1 CBM ≈ 1000 kg. Air freight uses 1 CBM ≈ 167 kg (L×W×H cm / 6000). Carriers may apply different divisors — check the tariff.
