Volumetric Peso Formulas

|---|---|---|
| Air freight (IATA) | L×W×H ÷ 6000 | L×W×H ÷ 366 |
| Couriers (varies) | L×W×H ÷ 5000 | L×W×H ÷ 305 |
| Sea freight | Usually real weight | — |
Ejemplo: Un/Una box 50×40×30 cm weighing 8 kg:
Volumetric weight = (50×40×30) ÷ 5000 = 60000 ÷ 5000 = 12 kg
Chargeable weight = 12 kg (higher than real 8 kg)
