Product and SKU commerce item quantities can be configured to be sold in fractional quantities. This means that a product or SKU can be sold in units such as half a pound or quarter of a liter. By default, fractional quantities are not enabled, but if working with products or SKUs that can be sold in this manner, you can easily implement them.
To enable fractional units within products and SKUs:
Enable fractional units as described in the Enabling Fractional Units in Products and SKUs section.
Configure the units of measure that the commerce items use, as described in the Configuring Units of Measure section.
To implement fractional units, a page developer makes updates to allow fractional quantities within the shopping cart page. Page developers can retrieve the fractional breakdown for a specified unit of measure using the UnitOfMeasureDroplet, as well as create quantity pickers or stepper controls in the UI. For information on working with the UnitOfMeasureDroplet, refer to the Guide to Setting Up a Store.
