Unit price is the cost for a standard amount of a product—such as cost per kilogram, cost per litre, or cost per item. It helps you compare differently-sized packs fairly.
The calculator converts each product’s quantity into a common base unit and then divides the price by that standardized quantity.
Unit Price = Price Ă· Quantity (in base units)
For weight: base unit is kg (g are converted to kg). For volume: base unit is litre (ml are converted to litres). For items: base unit is item count.
