How to find your Volumetric Weight for International Shipping?
In international Shipping, the parcel/shipment is first scaled and the weight is calculated. If it is 0.5, it is rounded to 1 kg. This applies to all numbers. Secondly, the volumetric weight is measured. Once done, the bigger of the actual weight vs volumetric weight is used to charge for shipping. This is the international standard and applies to cargo and courier services universally.

To find your volumetric weight, measure the Length, Width and Height of your box in centimeters or Inches. Multiple the length, width, height. If using centimeters, divide the total of the multiplication of length, width and height by 5000 to get your shipment weight. If using inch units, divide the total by 139.
