The Blood Sugar Level Calculator helps assess blood glucose readings by taking into account whether the measurement was fasting or post-meal, and the unit used (mg/dL or mmol/L). It classifies the reading as Low (Hypoglycemia), Normal, Prediabetes, or Diabetes, providing a quick reference for monitoring blood sugar levels. This tool is useful for daily tracking and understanding general ranges, but it is not a substitute for professional medical evaluation or diagnosis.
