Unit Price / Price-per-Unit Calculator normalizes package prices by mass, volume or item count so products can be compared on a common basis. The calculator keeps mass, volume and count dimensions separate. This prevents invalid comparisons such as treating every litre as one kilogram without a valid density relationship. How to use Unit Price / Price-per-Unit Calculator: Enter package price, quantity and unit. Review the normalized price for the appropriate dimension. Add products to compare packages with different sizes. Use a common dimension before deciding which product has the lower unit price. Common uses: Grocery comparison Package-size comparison Price per kg and gram Multipack cost analysis Can I compare kilograms and litres? Not directly. Mass and volume are different dimensions unless a valid density conversion is available for the specific substance. What is price per 100 grams? It is the normalized cost of 100 grams, useful for comparing many packaged foods with different package sizes. Can I compare multipacks? Yes. Use item count as the unit when the individual items are genuinely comparable.
