If the density is greater than one, the price will be higher per liter than per kg. Convert the price per kg to the price per liter or vice versa:

For example, if a product costs $18.00/l, divide by the density of 1.41 kg/l and the price is $12.77/kg.

Calculation: Price per liter / density = price per kilogram

Kilo price x density = liter price
