Volumetric Weight Formula
Volumetric weight is calculated by measuring the space your package occupies:
Length (cm) × Width (cm) × Height (cm) ÷ Volumetric Divisor
The standard volumetric divisor6000
Example:4 kg. If its actual weight is 2.5 kg, you will be charged based on the 4 kg volumetric weight.
