A1C to eAG Converter
Translate your A1C percentage into estimated average glucose levels.
HbA1c (Hemoglobin A1c) reflects your average blood sugar levels over the past 2-3 months.
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
eAG (Estimated Average Glucose) converts your A1C percentage into the same units (mg/dL or mmol/L) used by your daily glucose meter, making it easier to understand.

What is the difference between A1C and eAG?
A1C is a percentage that reflects long-term glucose control (2-3 months), while eAG translates that percentage into mg/dL or mmol/L—the same units you see on your daily glucose meter.
How accurate is this calculator?
This calculator uses the standard ADAG (A1c-Derived Average Glucose) study formula adopted by the American Diabetes Association. However, individual results can vary due to conditions like anemia or kidney disease.
