With this calculator you can compare the price of goods that have different packing sizes.

Usage: At first, type either the price per kilogram or per liter or type another amount (in gram or liter) and its price into the correspoding fields. Then type one or more other amounts (in gram or milliliter). After a click with the mouse on any free space of the window or on the "calculate" button you can read the prices for the other amounts in the right column, calculated with the same price per kilogram.
Move the mouse over a unit or click on it to read its full name. For another calulation type in the new values or click on the "reset" button before.

Example: In a shop 650 gram of some good cost 85 ¢. In another shop you pay 1.69 € for 1.2 kg of this good. Which price is better ?
Type "650" for the amount and "0.85" for the price into one of the rows of the table. After a click with the mouse on any free space of the window or on the "calculate" button you may already read the price per kilogram (1.308 €). Now type the amount "1200" for 1.2 kg into another row of the table. After another click with the mouse the result is calculated (1.57 €). The first shop had the better price.

- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
