Decoding Your A1c: How to Convert Your A1c to an eAG Blood Sugar Level
Understanding your blood sugar levels is crucial, especially if you're managing diabetes or at risk of developing it. Two key metrics doctors use are A1c and eAG (estimated Average Glucose). While both reflect your average blood sugar, they’re presented in different formats. This article will explain what A1c and eAG are, how to convert between them, and why these measurements are important for your overall health.
What is A1c?
The A1c test, also known as the hemoglobin A1c test, measures your average blood sugar level over the past 2-3 months. It works by measuring the percentage of your hemoglobin (a protein in red blood cells that carries oxygen) that is coated with glucose. The higher your blood sugar levels, the more glucose will attach to your hemoglobin.
Here's why A1c is valuable:
- Long-term View: It provides a broader picture than a daily finger-prick test, which only captures a snapshot in time.
- Convenience: You don’t need to fast before an A1c test.
- Diagnostic Tool: A1c is used to diagnose prediabetes and diabetes.
What is eAG?
eAG, or estimated Average Glucose, is another way of expressing your average blood sugar level. It's presented in the same units (mg/dL) as your daily blood sugar readings, making it easier for many people to understand. eAG is essentially the average blood sugar level that corresponds to a particular A1c value.
Why Convert A1c to eAG?
While your doctor will interpret your A1c results, converting it to eAG can help you better understand and visualize your blood sugar control. Many people find eAG more relatable than A1c percentages. This can lead to better self-management and improved adherence to treatment plans. Seeing your blood sugar in familiar terms can be incredibly motivating.

How to Convert A1c to eAG
The conversion between A1c and eAG is based on a mathematical formula. Here’s the standard formula:
eAG (mg/dL) = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, then:
eAG = (28.7 x 7) - 46.7 = 200.9 - 46.7 = 154.2 mg/dL
Therefore, an A1c of 7% corresponds to an eAG of approximately 154 mg/dL.
A1c to eAG Conversion Chart
To make things even easier, here's a conversion chart showing common A1c values and their corresponding eAG values:
| 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 | 11.0 |
| 9.0 | 212 | 11.8 |
| 9.5 | 226 | 12.6 |
| 10.0 | 240 | 13.4 |
| 10.5 | 255 | 14.2 |
| 11.0 | 269 | 14.9 |
| 11.5 | 283 | 15.7 |
| 12.0 | 298 | 16.5 |
Important Note: This chart provides approximate conversions. Individual results may vary. Consult your healthcare provider for a personalized interpretation of your A1c and eAG levels. The last column eAG (mmol/L) are sometimes used in other countries instead of eAG (mg/dL).
Understanding A1c and eAG Targets
Target ranges for A1c and eAG vary depending on individual factors like age, health conditions, and treatment goals. However, general guidelines include:
- Normal A1c: Below 5.7%
- Prediabetes A1c: 5.7% to 6.4%
- Diabetes A1c: 6.5% or higher
For most adults with diabetes, the American Diabetes Association (ADA) recommends an A1c target of less than 7.0%, which corresponds to an eAG of approximately 154 mg/dL. Talk to your doctor about what target is right for you.

Factors That Can Affect A1c Results
While A1c is a reliable indicator of average blood sugar levels, certain factors can influence its accuracy. These include:
- Anemia: Can falsely lower A1c.
- Kidney Disease: Can affect red blood cell turnover, impacting A1c.
- Hemoglobin Variants: Certain variations can interfere with the A1c test.
- Pregnancy: A1c levels may be lower during pregnancy.
If you have any of these conditions, discuss them with your doctor, as they may need to use alternative methods to monitor your blood sugar.
How to Improve Your A1c and eAG Levels
Lowering your A1c and eAG involves a multifaceted approach:
- Diet: Follow a balanced meal plan rich in fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and unhealthy fats. Consider consulting a registered dietitian for personalized guidance.
- Exercise: Regular physical activity helps improve insulin sensitivity and lower blood sugar levels. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Medication: If prescribed, take your diabetes medications as directed by your doctor.
- Monitoring: Regularly check your blood sugar levels and track your results. This helps you understand how your body responds to different foods and activities.
- Stress Management: Chronic stress can elevate blood sugar levels. Practice relaxation techniques like deep breathing, meditation, or yoga.
- Sleep: Aim for 7-8 hours of quality sleep each night. Lack of sleep can impair insulin sensitivity.
Conclusion
Understanding the relationship between A1c and eAG empowers you to take control of your diabetes management. By converting your A1c to an eAG, you can better visualize your average blood sugar levels and make informed decisions about your diet, exercise, and medication. Regular monitoring, coupled with healthy lifestyle choices, can help you achieve and maintain your target A1c and eAG, ultimately improving your long-term health and well-being. Remember to always consult with your healthcare provider for personalized advice and guidance.
