For example, an American customer buys a product after it is packaged.
The actual weight is 400 G. The first weight is 500 g, less than or equal to 500 g, calculated as 500 g.
Volume weight: After packaging, we will measure the actual volume of the package. The measured volume is 25 cm * 23 cm *22 cm. The formula for calculating the conversion of volume into weight is Length * width * height / 5000. Volume weight is 25 cm *23 cm * 22 cm / 5000 = 2.53 kg.
The actual weight of the package is calculated at 3kg shipping cost.
