A1c to Blood Sugar Conversion: Understanding Your eAG Number
Understanding your blood sugar levels is crucial for managing diabetes effectively. While you might be familiar with checking your blood sugar using a glucose meter, the A1c test offers a broader picture of your average blood sugar control over the past 2-3 months. Knowing how to convert your A1c result to an estimated average glucose (eAG) can provide valuable insights for your healthcare plan. This article will walk you through the A1c to blood sugar conversion process, explain the significance of your eAG number, and offer strategies to maintain healthy blood sugar levels.
What is the A1c Test?
The A1c test, also known as the glycated hemoglobin test, measures the percentage of your red blood cells that have glucose attached to them. Higher A1c levels indicate higher average blood sugar levels over the preceding months. This test differs from a daily blood sugar reading, which provides a snapshot of your glucose at a specific moment. The A1c test gives a more comprehensive view of your long-term blood sugar control, helping your doctor make informed decisions about your diabetes management plan.
The Significance of eAG (Estimated Average Glucose)
The eAG (estimated Average Glucose) provides an approximate average of your daily blood sugar levels based on your A1c result. The A1c to eAG conversion helps translate the A1c percentage into a more familiar blood sugar reading, often expressed in mg/dL (milligrams per deciliter). By understanding your eAG, you can better correlate your A1c results with your day-to-day blood sugar monitoring and dietary habits.

A1c to eAG Conversion Table
Here's a simplified table to help you quickly convert your A1c to an estimated average glucose (eAG):
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.2 |
| 8.5 | 197 | 10.9 |
| 9.0 | 212 | 11.8 |
Note: This table provides estimates. Always consult with your healthcare provider for personalized guidance and accurate interpretation of your A1c and eAG values.
How to Convert A1c to eAG Manually
You can also estimate your eAG using a simple formula:
- eAG (mg/dL) = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, the calculation would be:
- eAG = (28.7 x 7) - 46.7
- eAG = 200.9 - 46.7
- eAG = 154.2 mg/dL (approximately 154 mg/dL)
Many online A1c to eAG calculators are also available to make the process even easier.
What is a Healthy A1c and eAG Range?
Generally, for people with diabetes, the target A1c is often below 7%. This equates to an eAG of approximately 154 mg/dL. However, target ranges can vary based on individual factors like age, other health conditions, and the type of diabetes you have. It's crucial to discuss your individual target with your doctor. For those without diabetes, an A1c is typically below 5.7%, corresponding to an eAG of less than 117 mg/dL. An A1c between 5.7% and 6.4% indicates prediabetes.
Factors That Can Affect A1c Results
Several factors can influence your A1c test results, including:
- Certain Medical Conditions: Anemia, kidney disease, and liver disease can affect A1c accuracy.
- Hemoglobin Variants: Certain types of hemoglobin (e.g., sickle cell trait) can interfere with the A1c test.
- Ethnicity: Some studies suggest that certain ethnic groups might have slightly different relationships between A1c and average blood sugar.
- Age: A1c levels might naturally increase slightly with age.
If you have any of these factors, discuss them with your doctor to ensure accurate interpretation of your A1c results.

Lowering your A1c requires a combination of lifestyle modifications and, in some cases, medication. Here are some effective strategies:
- Follow a Healthy Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, and whole grains. Limit your intake of sugary drinks, processed snacks, and high-fat foods. Work with a registered dietitian for personalized meal planning.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise each week, such as brisk walking, cycling, or swimming. Strength training exercises can also help improve blood sugar control.
- Monitor Your Blood Sugar Regularly: Consistent blood sugar monitoring helps you understand how different foods, activities, and medications affect your glucose levels.
- Take Medications as Prescribed: If your doctor prescribes medication to manage your diabetes, take it as directed.
- Manage Stress: Stress can raise blood sugar levels. Practice stress-reduction techniques such as yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Lack of sleep can negatively impact blood sugar control. Aim for 7-8 hours of quality sleep each night.
- Work Closely with Your Healthcare Team: Regular check-ups with your doctor, diabetes educator, and other healthcare professionals are crucial for effective diabetes management.
Understanding Your eAG in Relation to Daily Blood Sugar Readings

Your eAG is an average value calculated from your A1c. It provides context for interpreting individual blood glucose readings taken throughout the day. Consider this example: If your eAG is 154 mg/dL (A1c of 7%), you wouldn't expect every blood glucose reading to be precisely 154 mg/dL. Some readings will naturally be higher (e.g., after meals), and others lower (e.g., before meals or after exercise). Your target range before meals may be 80-130 mg/dL, while your target range one to two hours after the start of a meal may be less than 180 mg/dL. Compare these daily numbers to your eAG to get an overall picture of your blood sugar control. If your daily blood glucose readings are consistently above or below your target ranges, discuss this with your doctor or diabetes educator.
Conclusion
Understanding the A1c to blood sugar conversion and your eAG number is an empowering step in managing your diabetes effectively. By using the conversion formulas and tables provided, you can translate your A1c percentage into a more relatable average blood sugar reading. Remember, a healthy A1c and eAG range is crucial for preventing long-term diabetes complications. By adopting healthy lifestyle habits and working closely with your healthcare team, you can achieve and maintain optimal blood sugar control, contributing to your overall health and well-being. Always discuss your specific A1c and eAG goals with your doctor for personalized guidance.
