空运计费重量计算器
空运计费重量（Chargeable Weight）取货物实际重量与体积重量（抛重）中的较大值。国际航空运输协会（IATA）标准换算系数为每立方米167公斤（即6000 cm³/kg）。本工具可帮助您在申请空运报价前，预算实际计费重量和运费成本。

Enter carton dimensions, piece count and gross weight to calculate airline chargeable weight using the IATA ÷6000 or express courier ÷5000 volumetric divisor. Compares actual vs volumetric weight and shows which the airline will bill.
IATA ÷6000 is standard for airline belly cargo and air freight. Express couriers (DHL, FedEx, UPS) use ÷5000.
Formula
Volumetric Weight (kg) = L × W × H (cm) × Pieces ÷ Divisor | Chargeable = MAX(Actual Weight, Volumetric Weight)
The IATA volumetric divisor of 6,000 converts cm³ into kilograms for pricing purposes. Express couriers use 5,000. When a shipment's volume-to-weight ratio is high (light but bulky), the airline charges based on volumetric weight rather than the lighter actual weight — ensuring revenue per unit of space, not just weight.
Worked Example
10 cartons · 80 × 60 × 50 cm · total gross weight 85 kg · IATA divisor 6,000:
Volume per carton = 80 × 60 × 50 = 240,000 cm³
Total volume = 240,000 × 10 = 2,400,000 cm³
Volumetric weight = 2,400,000 ÷ 6,000 = 400 kg
Actual = 85 kg → Chargeable = MAX(400, 85) = 400 kg
Despite 85 kg actual weight, the airline charges 400 kg. At $3.50/kg this is $1,400 — versus $297.50 on actual weight. The volumetric weight multiplier of 4.7× is why right-sized cartons and dense packing reduce air freight cost dramatically.

业务示例
场景：您需要空运一批电子产品从深圳到法兰克福，共5箱，每箱尺寸60×50×40厘米，每箱实际重量12公斤。
· 单箱体积重 = (60×50×40) ÷ 6000 = 20 kg（抛重）
· 单箱实际重量 = 12 kg
· 单箱计费重 = max(20, 12) = 20 kg（取较大值）
· 5箱总计费重 = 20 × 5 = 100 kg
· 若空运费率为HKD 28/kg，则运费预算约为 HKD 2,800
