# How to calculate mt CBM or chargeable weight?

Question

How can I calculate my shipment cubic meter(CBM) or chargeable weight?

Answer

In this case, we will use again our carton size as appear above

50*40*45(CM) and carton physical weight is 8KG.

For this order we will have 20 cartons in total.

There is a major difference in the formula between calculating regular air shipments vs express shipments

If we choose air regular:

Physical weight – 20 cartons * 8KG = 160KG

Chargeable weight – 50 40 45 = 90,000.

We need to divide 90,000 / 6000 = 15KG. This is our chargeable weight.

Now, let's take 20 cartons *15KG = 300KG.

300KG will be our chargeable weight even if our cargo physical weight is 160KG.

If we choose air express (by DHL / UPS / FEDEX):

Physical weight – 20 cartons * 8KG = 160KG

Chargeable weight – 50 40 45 = 90,000.

We need to divide 90,000 / 5000 = 18KG. This is our chargeable weight.

Now, let's take 20 cartons *18KG = 360KG.

360KG will be our chargeable weight even if our cargo physical weight is 160KG.
