CBM3 Product Facts and Free Access
CBM3.net is a browser-based CBM calculator and 3D container loading planner for importers, exporters, freight forwarders, e-commerce sellers and warehouse teams. Calculate shipment volume, compare load spaces, import cargo data and create practical 3D loading plans without registration, a trial clock or a paid membership.
What CBM3 does
CBM3 combines quick freight calculations with visual load planning, so users can move from carton dimensions to a practical container-loading plan in one browser-based workflow.
CBM and volume calculations
Calculate cubic metres or cubic feet for one or multiple cargo lines using metric or imperial units.
Volumetric weight
Compare dimensional weight with actual weight for freight quotation and shipment planning.
Load-space selection
Compare dry containers, reefers, trailers, ULDs, pallets and custom load spaces with Best Fit recommendations.
Interactive 3D loading
Review item labels, orientation, loading order, remaining space, operational rules and cargo placement in the selected load space.
Excel and CSV import
Import larger mixed-cargo lists instead of entering every carton or product line manually.
Reports, codes and saved plans
Create PDF-ready reports, reopen plans by code, share results and optionally save account-linked projects.
Weight distribution analytics
Review how cargo weight is distributed across the planned load before operational handoff.
Browser-based workflow
Use CBM3 online on modern desktop and mobile browsers without downloading or installing software.
Clear free access before any account
Registration is optional. It does not unlock the calculator or the 3D planner; it adds account-linked project saving, dashboard access and cross-device continuity.

Concise factual description
CBM3.net is a browser-based, free CBM calculator and 3D container loading planner. Users can calculate shipment volume, compare load spaces, import Excel or CSV cargo lists, create interactive 3D loading simulations and generate PDF-ready loading information without registration.
Guest calculations and local history remain in the active browser. An optional free account links saved projects to the user for persistent project management and cross-device continuity.
Loading simulations support planning and communication. Actual equipment dimensions, payload, axle limits, cargo strength, securement and applicable transport rules must be independently verified.
