  "description": "Calculate air freight dimensional weight and compare the common 6000 air freight divisor, 5000 express divisor, and 139 in/lb parcel divisor.",
  "answer": "Air freight dim weight is calculated from packed dimensions divided by a carrier divisor, with 6000 cm3/kg common for air freight and 5000 cm3/kg common for express.",

  "faq": [
    {
      "q": "What is the air freight dim weight formula?",
      "a": "Dim weight in kg equals length x width x height in centimeters x quantity divided by the carrier divisor."
    },
    {
      "q": "Which divisor should I use for air freight?",
      "a": "Use 6000 cm3/kg for standard air freight planning unless your quote specifies another divisor."
    },
    {
      "q": "Why compare 6000 and 5000 divisors?",
      "a": "A 5000 divisor produces 20% higher dim weight than 6000 for the same cargo, which often explains express quote differences."
    },
    {
      "q": "What is the 139 divisor?",
      "a": "The 139 in3/lb divisor is the common inch-pound parcel equivalent of about 5000 cm3/kg."
    },
    {
      "q": "Is dim weight the same as chargeable weight?",
      "a": "No. Dim weight must be compared with actual gross weight; the higher value is normally chargeable weight."
    },
    {
      "q": "What dimensions should I enter?",
      "a": "Use the outer packed carton, crate, or pallet dimensions that the carrier will measure."
