    • Frequency Adjustment: Calculates total daily dose based on administration frequency
  2. Safety & Precision
    • Real-time input validation
    • Decimal-point precision (supports 0.1 increments)
    • Clear unit labeling (milligrams)
  3. User-Centric Design
    • Instant auto-calculation as users type

How It Works

  1. Input Fields
    • Child’s Weight: Enter weight in kilograms (e.g., 12.5 kg)
    • Dosage per kg: Prescribed mg-per-kilogram ratio (e.g., 15 mg/kg)
    • Daily Frequency: Number of doses per day (e.g., 3 times daily)
  2. Automatic Calculations
    • Per Dose: Weight × Dosage-per-kg
    • Daily Total: Per Dose × Frequency

Example:

Weight: 10 kg | Dosage: 20 mg/kg | Frequency: 3x/day  
→ Per Dose: 200 mg | Daily Total: 600 mg
