How to use different UOMs?

Hi all,

I have two UOMs . 1) Gallon 2) Kgs

Conversation factor is 1 Gallon = 3.785Kgs.

Stock is always in Kgs.

But sometimes I raise sales order in kgs and sometimes in Gallons.

If I raise in kgs . there is no problem.

But if I raise order in Gallons, how stock will reduce as per Gallons?

Can anybody help me on this?

Thanks & Regards,

Saikrishna.
