Which products need it

- Fabric and products sold by the metre.
How it is calculated
A 250 g bag of coffee at 8,90 € is 35,60 € per kg. A 75 cl bottle at 12 € is 16 € per litre. The unit price follows the price, sales included.
Where to show it
Next to the price on product pages, in the shop and in the cart, smaller than the price but easy to read.
Per kg or per 100 g?
Per kg or per litre is the usual reference; per 100 g suits small quantities like spices or cosmetics.
Unitly calculates and shows the unit price from each product’s contents, for products and variations. See the demo.
