Product Manufactured :

1.  Toilet Cleaners are manufactured in (Liters)     and than the produced Toilet Cleaner is packed into 250 ml Bottles or 500ml Bottles and sold in terms of Bottles of 250mls or 500 mls.

Now I need to know how these products Toilet Cleaner 250ml and Toilet Cleaner 500ml UoMs should be configured properly under these Tabs of Products :

Information -->  UoM = ?
Procurements -->  Purchase Unit of Measuer = ?
Sales --->  Unit of Sale ,  UoS Coefficient = ?

Sales orders will be given in terms of No. of bottles (250ml or 500ml ) and according to the Sales Orders, that much amount of Litres of Toilet Cleaner will be manufactures.

I tried to follow this link
