It is important to know how much your item weighs so you can attach the correct postage. This is rounded up to 20, giving a dimensional weight of 20kg. For example, the dimensional weight of a 10kg item, which is 62cm long, 49cm wide and 39cm deep is (62x49x39)/6000 = 19.75. To calculate the dimensional weight, multiply the length in centimetres by the width by the depth and divide by 6,000.
