Formula unit prices: dry ounces are not fluid ounces

Calculate a compatible unit cost

Divide the full merchandise price by the total declared quantity in the same physical unit. A case needs its container count multiplied into that quantity. Our unit-cost tool accepts grams or dry ounces and deliberately does not calculate a feeding yield, mixing ratio or amount a child should consume.

Keep the decision in the right order

First establish the product your child can appropriately use with the relevant professional guidance. Then compare the exact eligible item and format across verified sellers. A low price on a different formula or on a toddler drink does not create a like-for-like alternative.

Work a transparent example

For two fictional powder packs, $30 for 15 dry oz is $2.00 per dry oz, while $38 for 20 dry oz is $1.90. The second has a lower quantity price in that example. These are teaching inputs, not observed offers, and they say nothing about nutritional suitability or feeding cost.

Before you decide

• Confirm mass versus volume.
• Include the whole case quantity.
• Keep actual offers separate from teaching examples.
