FAQ
Can I compare different units?
Yes for common matching unit families. The calculator can normalize pounds to ounces, kilograms to grams, liters to milliliters, and quarts to fluid ounces before ranking options.
Should I always buy the lowest unit price?
Not always. Storage space, freshness, quality, and whether you will use the full package can matter more than a small unit-price difference.
What if two packages use unrelated units?
Do not compare unrelated units such as pounds and sheets in the same calculation. Put food, paper goods, liquids, and count-based items into separate comparisons.
Does this include tax, coupons, or rewards?
No. Enter the shelf price you want to compare, or subtract a coupon manually first. The result is a shopping helper, not a full budget or financial planning tool.
