Translate Your Blood Sugar Results

Understanding your diabetes metrics shouldn't require a medical degree. Our A1C Calculator converts between your Hemoglobin A1C percentage (a 3-month average) and your estimated Average Glucose (eAG) in mg/dL. This helps you correlate your daily finger-prick readings with your long-term doctor's reports, giving you a clearer picture of your overall glycemic control.

The A1C-Glucose Relationship

The A1C test measures the amount of sugar attached to your red blood cells over their 3-month lifespan. However, most daily meters measure glucose directly. This tool uses the ADAG study formula: eAG = (28.7 × A1C) - 46.7. Use it to set realistic daily targets that align with your long-term health goals.

Health Fact: For most adults with diabetes, the American Diabetes Association recommends aiming for an A1C of less than 7%, which corresponds to an average glucose of about 154 mg/dL.
