Ever found yourself in this situation? A 3.8-liter jug costs R$ 28.99, while a 500 ml bottle goes for R$ 10.00. Maybe someone asks you that all the time:
Which one is the better deal?
It may seem like an easy answer, but when prices are close or the packaging varies a lot, the math can be misleading. That’s why we built this price per liter calculator, a quick and easy tool to help you make smarter, more economical decisions.

💡 If you want to compare just 2 products using the price per liter, just delete the price of the one listed in milliliters. It will be ignored in the calculation. This also works for any other comparison between 2 products.
If you want to learn how to do these calculations, take a look at the following information.
To properly compare price per liter, all products need to be in the same unit. Liters (L) are the standard, so the best approach is to convert everything to liters or milliliters (ml). Here’s how:
● We know that 1 liter = 1000 ml
● So:
500 ml ÷ 1000 = 0.5 L
Result: 500 ml is equal to 0.5 liters
● We know that 1 liter = 1000 ml
● So:
3.8 L × 1000 = 3800 ml
Result: 3.8 liters is equal to 3800 ml
These conversions help you accurately calculate and compare the price per liter using the formula:
Price per liter = Price / Quantity in liters
If your quantity is in milliliters, divide the price by the number of milliliters to get the cost per milliliter, then multiply by 1000 to convert it to cost per liter:
Price per liter = (Price / Quantity in ml) x 1000
