Hi Asha, The unit of measure is automatically set based on the currency selected in the form. Lbs will be the unit of measure for products sold by weight in USD. If the weight is less than 1lbs, it will be displayed in Oz. For example, if you enter 0.5 as the weight option for a product, it will be displayed as 8oz. If the weight is greater than 1lbs, it will be displayed in Lbs. For example, if you enter 2 as the weight option for a product, it will be displayed as 2lbs.
