📏 How the calculator works
The calculator uses verified powder density data from manufacturer labels. It accounts for powder displacement — the additional volume each gram of powder adds to the solution (using 30 mL/fl oz for clinical consistency).

⚠️ Osmolality warning
Concentrating formula increases osmolality. Values above 400–450 mOsm/kg may not be appropriate for preterm infants. Always check with clinical team before fortifying to >27 cal/oz.

⚠️ Preterm/NICU use
For preterm infants, fortification targets and approach should be directed by a registered dietitian or neonatologist. Monitor growth parameters regularly.

🧮 Scoops in practice
Scoops are measured as level, unpacked scoops. For fractions: ½ scoop = half level scoop. For very small fractions, weigh powder using a digital scale for accuracy.

🍼 Breast milk fortification
Caloric density of breast milk varies (14–22 cal/oz). Default is 20 cal/oz. For medically precise calculations in NICU, use actual measured caloric density. Add powder just before feeding.

📋 Data disclaimer
Formula compositions may change. Always verify against current manufacturer label. This tool is for educational guidance only — not a substitute for clinical dietitian review.
