Calculate a unit price
Formula: Unit price = price / quantity in kg, L or items
The result is per kilogram for g/kg, per liter for mL/L, or per item. Example: 3 for 500 g → 6 per kg. Quantity must be strictly positive. No mass/volume conversion or additional fees.

Compare two offers
Formula: Compare price A / quantity A and price B / quantity B
Compare the same currency and quantity type. g and kg are compatible, as are mL and L; mass, volume and items cannot be mixed. Comparison uses exact prices before display rounding: two identical displayed prices can still have a cheaper offer.
