Unit Price Calculator
Calculate and compare prices per kilogram, liter, meter, or item across different package sizes.
How to calculate unit price
Divide price by quantity expressed in a common unit. The calculator normalizes grams to kilograms, milliliters to liters, and centimeters to meters before comparison.
Compare different package sizes
The package with the lower total price is not always the better value. Price per kilogram, liter, meter, or item gives different quantities a common reference.
Percentage difference
The monetary difference uses the shared base unit. The percentage shows how much the higher unit price exceeds the cheaper one, using the cheaper price as its denominator. Currency is not converted.
Compatible units
Mass, volume, length, and individual items are compared separately. Liters cannot be compared with kilograms because they measure different dimensions.
