Hi Laura,

Before you change any of the units of measure on the Master Item or an Alternate Price List Item, you first need to define the units of measure conversion factors.

If you allow Fractional Quantities for your items, then your conversion factors may also use decimals or be less than one (ie 0.25 or 1.55). If you do not allow Fractional Quantities, then the conversion factors must be whole numbers and cannot be less than one (ie 12 or 100).

Once your conversion factors are defined for an item, you can change the stocking, pricing or costing units as required. Indeed if you change the default stocking unit, you may want to re-adjust the default pricing or costing units - all three units don't have to be the same. The Stocking unit is used when doing inquiries or reports on an item. The Pricing unit is a default when selling the item. The Costing unit is a default when receiving the item.

To expand on Andrew's answer with greater precision on the selling unit price, you need to create an Alternate Price List item in order to set the number of decimals of the unit price (up to 6). This cannot be done on the Master item.
