How it works
- Unit price divides total price by the quantity contained in the product.
- Products should be compared using the same measurement unit.
- The calculator does not automatically convert between grams, kilograms, milliliters, liters, ounces, or other units.
Unit Price = Product Price / Quantity
Frequently asked questions
Can I compare grams with kilograms?
Not directly. Convert both quantities to the same unit before comparing.
Does a larger package always have a lower unit price?
No. Calculate both unit prices to verify which product actually offers the lower cost per unit.
Can I compare items instead of weight?
Yes. Use the same unit label and enter the number of items as the quantity.
