Short answer: Example: a 40 × 30 × 20 cm box has a volume of 24,000 cm³; divided by 5000 that is 4.8 kg, so at an actual weight of 2 kg the chargeable weight is 4.8 kg.

With divisor 6000 the same box gives 4 kg, and with 8000 it gives 3 kg; the actual 2 kg is still lower, so size decides in each case. These numbers are illustrative, not a GTBuy parcel.

5000, 6000 and 8000 are divisors commonly used by carriers for centimetres and kilograms; which one applies depends on the shipping line, so check the estimate shown by GTBuy. This tool shows weights only, not prices or delivery times, and runs in your browser.
