  "description": "Keyword-variant calculator for air freight volume weight, using carton dimensions and a carrier divisor to calculate the volume-based kg used before chargeable-weight comparison.",

    {
      "q": "What is air freight volume weight?",
      "a": "Air freight volume weight is the kilogram value created from packed dimensions. Airlines use it to price light bulky cargo that consumes aircraft space."
    },
    {
      "q": "What is the formula for air freight volume weight?",
      "a": "Volume weight in kg equals length x width x height in centimeters x quantity divided by the carrier divisor."
    },
    {
      "q": "What divisor should I use?",
      "a": "Use 6000 for standard air freight unless your quote says otherwise. Use 5000 for many express or courier-style services."
    },
    {
      "q": "Is volume weight the same as volumetric weight?",
      "a": "Yes in most freight quotes. This page targets the \"volume weight\" wording; the canonical broader page is /tools/volumetric-weight-calculator-for-air-freight/."
    },
    {
      "q": "Is volume weight the same as chargeable weight?",
      "a": "No. Chargeable weight is the higher of actual gross weight and volume weight."
    },
    {
      "q": "Should I measure cartons or products?",
      "a": "Measure the outer packed cartons or pallet dimensions as tendered to the forwarder, not the product size inside the carton."
    },
    {
      "q": "When does volume weight exceed actual weight?",
      "a": "With a 6000 divisor, volume weight exceeds actual weight when cargo density is below about 167 kg per CBM."
