Volumetric Weight Explained: Measure in cm, Divide by 6000 or 8000 Why a light box can cost more A light parcel can still take up a lot of space. That is why shipping services may compare actual weight with volumetric weight. Let's make the calculation simple, with From China Hub. Measure the packed parcel Seal the parcel first. Measure the maximum outside length, width, and height in centimeters. For our example, the box is sixty by forty by forty centimeters. Include the packaging, not just the product inside. Start with the space it occupies Multiply length, width, and height. Sixty times forty times forty equals ninety-six thousand cubic centimeters. This is volume, not weight. Dividing by one million gives zero point zero nine six cubic meters, also called C B M. Same box. Different divisors. To estimate volumetric weight in kilograms, divide the cubic centimeters by the channel's divisor. Ninety-six thousand divided by six thousand is sixteen kilograms. Divided by eight thousand, it is twelve kilograms. Some services use five thousand or another rule. Use the divisor of your selected channel. Compare with the scale weight A common starting comparison uses the higher of actual and volumetric weight, before channel-specific rules. Suppose the actual packed weight is ten kilograms. Before rounding, the higher comparison weight is sixteen kilograms with a six-thousand divisor, or twelve with eight thousand. If the actual weight is twenty kilograms, twenty is higher in both examples. Bulging packaging counts too A bulging carton can be larger than the dimensions printed on it. Measure the farthest outside points, including bulges. Do not squeeze the box to get a smaller measurement. A carrier may measure it again. Imagine a box around the shape For an irregular parcel, imagine the smallest rectangular box that fully surrounds it. Use that box's maximum length, width, and height. Do not subtract empty corners. A sixty by forty by fifty centimeter envelope gives twenty kilograms when divided by six thousand. Measure. Compare. Get your quote. These are basic examples before channel-specific rounding or minimum charges. Multiple parcels may also have different calculation rules. A larger divisor does not automatically mean a lower total price. Enter your packed dimensions and actual weight at From China Hub dot com, then compare available shipping services.
