Multiple Base Unit of Measure

Hi there,

Please advise.  I have a request to create several base unit of measures for a material.  Industry is Pharmaceutical.

Eg Goods received 1 x box, each box contains 10 packs of pills.  Each pack of pills contains 12 pills.  We want to be able to dispense/sell either a pack as well as be able to dispense/sell single pill from the pack.

I am not to familiar on how to set this up, kindly provide the steps.

Thanks in advance
