About this calculator
The Unit Price calculator helps compare the actual cost of products based on their volume in liters. It calculates the price per liter, allowing you to evaluate which options are more cost-effective, especially for items like sodas, milk, or oils. Simply enter the total product price and its quantity in liters.
The formula used is (Price × 1000) / Quantity, where the price is multiplied by 1000 to convert liters to milliliters, standardizing the unit of measurement. This ensures the result is in milliliters, making direct comparisons between different size packages easier. For example, R$ 3.00 for 1.5 liters and R$ 2.50 for 1 liter can be accurately compared.
Use this tool when you want to discover which packaging offers the lowest unit cost. It's ideal for comparing brands, promotions, or varied sizes. However, it only works for products measured in liters; for weights (kg, g) or counts, other calculators are needed.
Important: always confirm that the entered quantity is in liters. Errors in this unit will affect the calculation's accuracy. Additionally, disregard taxes or extra fees not included in the product's total price.
