Unit price calculator
Calculate and compare the unit price of products (per kilogram, liter or item) to make better purchasing decisions.
Why unit price matters
Unit price helps you compare products with different package sizes. By converting everything to a common reference (€/kg, €/L, or €/item), you can quickly spot the best value and avoid misleading “bigger box” pricing.
- Compare two brands even if quantities differ.
- Check promotions: sometimes “-20%” is still more expensive per unit.
- Use realistic units (kg for solids, liter for liquids, item for pieces).
