- Use consistent units for comparison. For food: oz, grams, or pounds. For liquids: fl oz, ml, or liters. Match units across products.
- Larger packages aren't always cheaper per unit. Always calculate unit price to find the true best value.
- The calculator automatically identifies the best value product (lowest unit price). Look for the checkmark indicator.
- Unit price helps you make informed shopping decisions. Compare before buying to ensure you get the best deal.
