Enter your parcel's length, width and height to instantly calculate its volumetric (dimensional) weight in kg and lbs.
Formula: (L × W × H) ÷ 5000 = kg
Volumetric weight is the calculated weight based on the length, width and height of a parcel converted to volumetric kilograms. The formula used varies by courier and service. Carriers charge based on whichever is greater — the actual weight or the volumetric weight — to account for large but light parcels that take up significant space.
Different courier companies use different metrics, but the most common method is to multiply the 3 parcel dimensions in centimetres and divide by 5,000.
All measurements should be in centimetres. If measuring in inches, divide by 305 instead. To convert to pounds, multiply the kg result by 2.2046.
The bigger an item is, the more room it takes up on a vehicle or aircraft, and therefore the more it costs to send. If an item is large but light, the price will be based on the size rather than the weight. Understanding this helps you avoid unexpected shipping costs — always compare both before booking.
