Container CBM Calculator

Container CBM Calculator is a professional logistics toolkit that brings container loading, CBM and freight weight calculations together in one app. Works fully offline — no sign-up, no account.

3D CONTAINER LOADING CALCULATOR
Choose a standard container type (20GP, 40GP, 40HC, reefer and more) or enter internal dimensions manually. Add your cargo — cartons, pallets, cylinders, big bags — and a 3D bin-packing algorithm calculates how many pieces fit and exactly where they go, shown in an interactive 3D scene.
• Used volume, used weight and unplaced pieces at a glance
• Cargo is kept upright, the way it is really loaded
• Share the loading plan as an image or save it to your gallery
• Save your calculations as reusable plans

CBM AND CHARGEABLE WEIGHT CALCULATOR
Work out cubic meters (CBM) and the chargeable weight your carrier will actually bill:
• Sea LCL — weight or measurement (W/M), whichever is greater
• Air freight — volumetric weight with the 1:6000 divisor
• Road freight — 1:3000 divisor
• Express courier — 1:5000 divisor
Enter package by package or as totals. Switch between cm/inch and kg/lb; imperial users also see cubic feet. Share the full result — dimensions, volume, gross weight and chargeable weight — as text to WhatsApp or email in one tap.

CONTAINER NUMBER CHECK (ISO 6346)
Enter the 4-letter owner code and 6-digit serial number; the ISO 6346 check digit is calculated instantly and the number is validated for you.

ISO CONTAINER TYPE REFERENCE
Decode ISO 6346 size and type codes such as 22G1, 42G1, 45G1, 22R1, 45R1, 22T1 and 45U1. For each type you get:
• Internal dimensions, door opening, tare, max payload and capacity

• Illustrations of the container body
• Search by code or name
Covers 20ft and 40ft, High Cube, Reefer, Open Top, Flat Rack, Tank, Bulk and ventilated containers.
