Baby Formula Dosage Calculator
Calculate exact formula powder and water ratios for baby bottles. Features a database of scoop sizes for major brands (Similac, Enfamil, Nan) to prevent dosage errors.
About
Preparing infant formula requires strict adherence to manufacturer ratios to maintain the correct caloric density (standard 20 kcal/oz) and osmolarity. Using too much powder can cause dehydration and renal strain, while too little leads to nutritional deficits. This utility solves the common problem of estimating tin longevity and bulk preparation.
Scoop sizes vary significantly between brands (e.g., 4.4g vs 8.8g), and international differences in spoon calibration often confuse parents. By inputting the specific scoop weight or selecting from a pre-filled database of global brands, this tool calculates the precise total grams of powder needed for a day's supply and estimates how long a bulk tin will last.
Formulas
To calculate the total powder mass (Mpowder) required for N bottles of volume Vbottle:
Where Rwater is the water volume per scoop (e.g., 30ml or 60ml) and Wscoop is the weight of one scoop. The days a tin lasts (Dtin) is found by:
