    {
      "q": "What does a CBM calculator for shipping calculate?",
      "a": "It calculates shipment volume in cubic meters and cubic feet from outer packed dimensions and quantity, then adds ocean and air volume-weight context for freight planning."
    },
    {
      "q": "Is this the canonical CBM calculator?",
      "a": "This is the shipping-focused CBM variant. The broader canonical calculator is /tools/cbm-calculator/, and related wording variants include /tools/calculator-cbm/ and /tools/free-cbm-calculator/."
    },
    {
      "q": "Can I use this for pallets?",
      "a": "Yes. Select pallet as the package type and enter the palletized outside length, width, height, quantity, and optional gross weight."
    },
    {
      "q": "How does gross weight affect the result?",
      "a": "Gross weight is optional. When entered, the widget compares actual gross weight against ocean volume weight and air volume weight so you can see which basis may drive planning weight."
    },
    {
      "q": "Should I enter product dimensions or carton dimensions?",
      "a": "Use outer shipping carton, crate, or pallet dimensions because freight providers measure the packed unit loaded into the truck, container, or aircraft."
