Shipping Container Load Calculator
Estimate how many items fit in a 20-foot or 40-foot shipping container based on item dimensions and weight, accounting for both cube and weight limits. Use it for ocean-freight planning, supply-chain sourcing decisions, and figuring out how to consolidate inventory across containers.

Package Optimization Calculator
Estimate the total packaging cost — both surface material and volume-based filler — for a box sized to fit a specific item with safety padding. Useful for finding the lowest-cost packaging that still protects goods and minimizes dimensional weight.
