Unit Price Formula:
Price per unit = Total Price / (Quantity x Unit factor)
All quantities are normalized to a common base unit (oz, g, ml, or count) for comparison. lb converts to oz, kg to g, L and fl oz to ml.
Unit price is the cost per standard unit of measure (e.g., per ounce, per gram, per milliliter). Comparing unit prices lets you identify the best value regardless of package size, since larger packages are not always cheaper per unit.
All weight units are normalized to ounces or grams for comparison. Pounds are converted to ounces (1 lb = 16 oz) and kilograms to grams (1 kg = 1000 g). This ensures a 2 lb bag and a 30 oz bag are compared on equal footing.
All volume units are normalized to milliliters. Liters (1 L = 1000 ml) and fluid ounces (1 fl oz = 29.5735 ml) are converted before comparison.
No — weight and volume measure different physical properties and cannot be directly compared. This calculator normalizes within each type (weight units together, volume units together). Only compare products with compatible unit types.
Usually yes, but not always. Warehouse club sizes can have lower unit prices, but buying more than you will use before expiration wastes money. Always factor in shelf life and storage when deciding on quantity.
Best Value is the product with the lowest price per base unit among the valid entries you entered. It indicates which product gives you the most quantity for your money.
