Your purchase notes
Keep the details in one place.
A serving jug and a graduated measuring jug do different work. Choose the purpose before comparing capacity and material.
For measuring, check the marked units and scale. For serving, look at the handle, spout and the shelf or fridge space where the jug will sit.
Compare the cost per unit
Choose one consistent unit: pieces, kilograms, litres or prepared litres, as appropriate. Divide total cost by the quantity. Do not compare unlike product types on price alone.
