Volume Weight Calculator

Useful volume weight calculator to convert volume to weight by dimensions for your air-, sea- or road freight shipments.

Weight/Volume Ratio

Type of transport	Volume calculation
Air freight	1 m³ = 167 kg
Truck	1 m³ = 333 kg
Sea freight	1 m³ = 1000 kg

How is airfreight calculated?

Prices (airfreight rates) are always quoted per kg/6 dm³. It can also be called the volume ratio 1 : 6 or 1 m3 = 167 kg. That means you either pay for the weight or the space necessary for the transport of your consignment.

The calcuation is based on the following equation regardless of whether youre paying for the weight or the space:

Length (cm) x width (cm) x height (cm) / 6000 (equals the volume weight in kg)

Example 1

You are sending 1 crate weighing 80 kg and the dimensions of the crate are 50 x 50 x 50. As the actual weight of 80 kg is higher than the volume weight (20.83 kg) the 80 kg are calculated as the freight weight.

You multiply:
50 x 50 x 50 cm = 125,000 cm3
You divide: 125,000 cm3 by 6000 = 20.83 kg volume weight

Example 2

You are sending 8 boxes with a total weight of 45 kg. All the boxes are the same size (each box is 60 x 40 x 20 cm). As the volume weight of 64 kg is higher than the actual weight (45 kg) the 64 kg are calculated as the freight weight.

You multiply:
8 boxes x 60 x 40 x 20 cm = 384,000 cm3 You divide: 384,000 cm3 by 6000 = 64 kg volume weight
