Ubercart is flexible in the way it formats currency, weight, unit measurements, and dates. The "Length format" tab, accessed from Store » Configuration » Store (/admin/store/settings/store), allows you to select the default unit of measure for product dimensions, as well as the way lengths will be displayed to your customers. Note that product information may be entered using any length units; this section controls how that information will be displayed to the customer.
