Use your average glucose to estimate A1C.
This uses the ADAG relationship: A1C (%) ≈ (eAGmg/dL + 46.7) / 28.7. For mmol/L, we convert by mg/dL = mmol/L × 18.

Estimate A1C from Average Glucose
A1C (also called HbA1c or glycated hemoglobin) is a blood test that shows your average blood glucose levels over the past 2–3 months. Instead of capturing daily ups and downs, it reflects how much sugar is “sticking” to your red blood cells. For most people, an A1C below 5.7% is considered normal, 5.7–6.4% signals prediabetes, and 6.5% or higher suggests diabetes. Lowering your A1C through balanced nutrition, regular exercise, stress management, and medications (if prescribed) helps reduce the risk of complications and supports long-term health.
Are you ready to take the first step?
Start small and make it stick: understand your mornings (dawn phenomenon and feet-on-the-floor), take a quick 10-minute walk after meals, build protein-forward plates with smarter carbs, and track what works with your CGM or meter. MetaboAI gives you bite-size guidance, an A1C estimator, and practical checklists, no overwhelm, just simple actions you can do today. Ask a question in the chat, try one change this week, and watch your numbers start moving in the right direction.
