What’s Your eAG? The A1c to Estimated Average Glucose Conversion Explained
Understanding your blood sugar levels is vital for managing diabetes or prediabetes. Two common measurements are A1c and estimated Average Glucose (eAG). While A1c provides a long-term view of your blood sugar control, eAG offers a more day-to-day perspective. In this article, we'll delve into what eAG is, how it's calculated from A1c, and why both are important for effective diabetes management.
Understanding A1c: The Long-Term View
The A1c test, also known as glycated hemoglobin, measures the percentage of your red blood cells that have glucose attached to them. This gives you an average picture of your blood sugar levels over the past 2-3 months. It’s a crucial indicator of how well your diabetes management plan is working. A higher A1c typically means higher average blood sugar levels and a greater risk of diabetes complications.
- Why is A1c Important? The A1c test is used to:
- Diagnose prediabetes and diabetes.
- Monitor blood sugar control over time in people with diabetes.
- Assess the effectiveness of a diabetes treatment plan.
What is eAG (Estimated Average Glucose)?
Estimated Average Glucose (eAG), also known as average blood sugar, is an estimate of your average glucose level based on your A1c result. It's essentially a translation of your A1c percentage into the same units (mg/dL) that you're familiar with if you regularly check your blood sugar with a glucose meter.
Think of A1c as telling you the average height of all the trees in a forest, while eAG tells you the average height in more familiar terms, like feet instead of meters.
How is eAG Calculated from A1c? The Conversion Formula
The relationship between A1c and eAG is a linear one, meaning there's a fairly predictable formula to convert one into the other. The most widely used formula for this conversion is:
eAG (mg/dL) = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, your estimated average glucose 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.

Here’s a handy chart to quickly convert your A1c value to the corresponding eAG value. This is especially useful for quick reference without having to do the calculation.
| 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: The mmol/L (millimoles per liter) is another unit for measuring blood glucose levels used in some parts of the world. This table provides both mg/dL and mmol/L equivalent for eAG values.
Why Both A1c and eAG are Important
While eAG is derived from A1c, presenting it as a number you're familiar with can make it easier to understand your blood sugar control.
- A1c: Provides a comprehensive, long-term overview. It's less susceptible to day-to-day fluctuations.
- eAG: Translates A1c into a more relatable daily average. This can help you connect your A1c results to your daily blood sugar readings and how your lifestyle choices (diet, exercise) impact your glucose control.
Both measurements play crucial roles in diabetes management, helping you and your healthcare provider make informed decisions about your treatment plan.
Target A1c and eAG Ranges: What's Considered Healthy?
Target ranges for A1c and eAG can vary depending on individual factors such as age, overall health, and other medical conditions. However, general guidelines exist:
-
For most adults with diabetes:
- A1c: Less than 7%
- eAG: Less than 154 mg/dL
-
For some individuals, a less stringent goal may be appropriate: Your doctor might recommend slightly higher targets depending on your specific needs.

It is crucial to discuss your target A1c and eAG with your doctor, as they can provide personalized recommendations based on your health profile.
Factors Affecting A1c and eAG Accuracy
While A1c and eAG are valuable tools, certain factors can influence their accuracy:
- Anemia and Hemoglobinopathies: Conditions affecting red blood cells can impact A1c results.
- Kidney Disease: Can lead to inaccurate A1c readings.
- Pregnancy: A1c targets may be different during pregnancy.
- Ethnicity: Some studies suggest that certain ethnic groups may have different relationships between A1c and average glucose levels.
If any of these factors apply to you, your healthcare provider may use alternative methods to assess your blood sugar control, such as continuous glucose monitoring (CGM).
Taking Action Based on Your A1c and eAG
Knowing your A1c and eAG values is just the first step. Here's how to use this information to improve your blood sugar control:
- Consult with Your Doctor: Discuss your results and any necessary adjustments to your medication, diet, or exercise plan.
- Set Realistic Goals: Work with your healthcare provider to set achievable targets for A1c and eAG.
- Monitor Your Blood Sugar Regularly: If you're on insulin or certain oral medications, regularly checking your blood sugar at home can help you understand how your daily habits affect your glucose levels.
- Make Lifestyle Changes: Adopt a healthy diet, engage in regular physical activity, and manage stress to help improve your blood sugar control.
