HbA1c ↔ Average Glucose Converter
Translate HbA1c (%) into estimated average glucose and back — the ADAG-study formula every diabetic needs.
HbA1c reflects ~3 months of average glucose (red cells live ~120 days) — the ADAG study gave it a meaning patients feel: 7% ≈ 154 mg/dL average, each 1% ≈ ~29 mg/dL. Anchors: 6% = 126, 8% = 183, 9% = 212. Caveat: anaemia, pregnancy and some haemoglobin variants distort HbA1c, so it can disagree with meter averages — a real clinical conversation, not an error.
