Weight and volume

Any business that is carrying goods, needs to calculate both volume and weight. The volume may also dictate the terms of pricing.  JetCarrier operates with a 1:4,5 factor on air freights and 1:1 on sea freight. Basicly this means that an air package may have a volume that is 4.5 times bigger than its actual weight. For sea freight we have no factor and 1 kg = 1 dm3.

How much is 1 dm3? 1 dm3 equals approx. 1 liter of water. Imagine a juice box of 1 liter, it weights approx 1 kg and its volume is of course 1 liter (= 1 dm3). This means that you can send an air freight package with a weight of 1 kg and a volume of 4 liters (4 dm3) for the price of 1 kg according to our price list. See below for given examples for both air- and sea freight.

Why cant you just use actual weight when invoicing? This would of course have been the easiest solutions for our customers, but it has some serious negative side effects. Some items barely have any weight vs. its volume. A pillow may only weight 100 grams but takes a lot of space. If we are to send 10 000 pillows we would most likely fill up the airplanes cargo space, but only pay for 1000 kg worth of freight. So in the end the conclusion is: volume also is a freight related cost.
