Great Module and use it all the time

However with shippers now getting a bit snarky over bulky items it has created a problem for us and I dare say quite a few others.

This module relies totally on weight. Is there a way to to get it to convert volume to weight.

I see it working as such

If a product has it's height x length x width set it calculates the corresponding "determined" weight and if higher it uses this as the basis for calculating the shipping cost.

Example using beans for a bean bag

Actual weight is 1.5 kg
Length 120cm
Width 20cm
Height 20cm

This gives a cubic measurement of 0.048cubic metres. If a shipper calculates a cubic metre as being 200kg this would make the determined weight 9.6kg and that is what they would charge.

They current module would need an alteration to
1. Determine if volume measurements exist for the item
2. If they do calculate the "determined weight"
3. Use the determined weight instesd of the physical weight

The admin module would also require a volume weight field for working this out. ie 1 volume unit = xxx physical weight unit.

A slight alternative is doing this at the end of the order - that is all item volumes are calculates at the end of the order and depending on which is higher - the physical weight or the determined weight this is used for the shipping calculation.

Any ideas on this one?

Thanks
