A1c to eAG Conversion: How to Translate Your A1c to Average Blood Sugar
Understanding your A1c level is crucial for managing diabetes and prediabetes. But what does that number really mean? This article breaks down the A1c to eAG conversion, helping you translate your A1c result into a more familiar metric: your average blood glucose (eAG). We'll cover how to calculate the conversion, why it's important, and what those numbers indicate about your overall health.
What is A1c?
The A1c test, also known as glycated hemoglobin, measures your average blood sugar level over the past 2-3 months. Unlike a daily blood sugar test that captures a snapshot in time, the A1c test provides a broader picture of your blood sugar control. It works by measuring the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels, the more glucose attaches to your red blood cells.
Understanding the A1c test and its implications is essential for effective diabetes management.
What is eAG?
eAG stands for estimated Average Glucose. It represents the average blood sugar level over a period, typically corresponding to the time frame covered by the A1c test. The eAG is expressed in milligrams per deciliter (mg/dL), the same units used for your daily blood sugar readings. This makes it easier to understand compared to the percentage format of the A1c. The goal of the A1c to eAG conversion is providing a relatable, easy to understand measure for managing diabetes.
Why Convert A1c to eAG?
Converting your A1c to eAG offers several benefits:
- Easier Comprehension: Many people find it easier to understand blood sugar levels in mg/dL rather than as a percentage.
- Improved Diabetes Management: Seeing the eAG can help you better understand how your diet, exercise, and medication are affecting your average blood sugar.
- Enhanced Communication with Healthcare Providers: You can use the eAG to have more informed discussions with your doctor about your diabetes control.
- Clearer Goals: The A1c to eAG conversion can help you set and track progress toward specific blood sugar targets.
The A1c to eAG Conversion Formula
While there are online calculators that can perform the A1c to eAG conversion, understanding the formula can be helpful. The generally accepted formula is:
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 = 200.9 - 46.7 = 154.2 mg/dL
Therefore, an A1c of 7% corresponds to an eAG of approximately 154 mg/dL.

The following table provides a general correlation between A1c values and their corresponding eAG levels:
| 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 | 15.0 |
| 11.5 | 283 | 15.8 |
| 12.0 | 298 | 16.6 |
Note: mmol/L is the unit used in some countries instead of mg/dL for blood glucose measurement. Consult your healthcare provider for clarification on which unit they use.
What Do Your A1c and eAG Values Mean?
Your A1c and eAG values provide valuable information about your blood sugar control:
- Normal: An A1c below 5.7% (eAG < 114 mg/dL) is considered normal.
- Prediabetes: An A1c between 5.7% and 6.4% (eAG 114-137 mg/dL) indicates prediabetes. This means you have a higher risk of developing type 2 diabetes.
- Diabetes: An A1c of 6.5% or higher (eAG ≥ 140 mg/dL) indicates diabetes.
The American Diabetes Association (ADA) generally recommends an A1c target of less than 7% for most adults with diabetes, which translates to an eAG of less than 154 mg/dL. However, individual goals may vary based on factors such as age, overall health, and the presence of other medical conditions. Work with your healthcare provider to determine the most appropriate target for you.
Factors That Can Affect A1c Accuracy
It's important to note that certain conditions can affect the accuracy of the A1c test. These include:
- Anemia: Conditions that affect red blood cell production, like anemia, can impact A1c results.
- Hemoglobinopathies: Certain genetic variations in hemoglobin can also influence A1c levels.
- Kidney Disease: Chronic kidney disease can sometimes lead to inaccurate A1c readings.
- Pregnancy: A1c targets for pregnant women with diabetes are often lower due to increased risk.
If you have any of these conditions, talk to your doctor about whether the A1c test is the most appropriate measure of your blood sugar control.

- Follow a Healthy Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean protein, and whole grains. Limit your intake of sugary drinks, processed foods, and unhealthy fats. Consider consulting a registered dietitian for personalized guidance.
- Exercise Regularly: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. Include strength training exercises at least twice a week.
- Monitor Your Blood Sugar: Regularly check your blood sugar levels as recommended by your doctor. This will help you understand how your diet, exercise, and medications are affecting your blood sugar.
- Take Medications as Prescribed: If you take medication for diabetes, it's essential to follow your doctor's instructions carefully. Don't skip doses or change your dosage without talking to your doctor.
- Manage Stress: Stress can raise blood sugar levels. Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of sleep per night. Poor sleep can negatively impact blood sugar control.
The Importance of Regular Monitoring and Communication
Regular monitoring of your A1c and eAG, along with consistent communication with your healthcare team, is crucial for managing diabetes and prediabetes effectively. By understanding the relationship between these metrics and taking proactive steps to improve your blood sugar control, you can reduce your risk of diabetes-related complications and improve your overall health. Remember, small changes can make a big difference over time. Don’t hesitate to seek guidance from your doctor, diabetes educator, or registered dietitian to create a personalized plan that works for you. The A1c to eAG conversion is simply one tool among many that helps with understanding your health.
