Frequently Asked Questions
How do I compare products by unit price?
Enter the price and quantity for each product, select the unit, and the calculator shows the price per unit for each. The best value is highlighted in green.
Can I compare products with different units?
Only products with the same unit type can be meaningfully compared. Compare oz to oz or kg to kg. Comparing oz to L would require unit conversion first.
