A Simple A1c Calculator and Guide to Estimated Average Glucose (eAG)
Understanding your blood sugar levels is crucial for managing diabetes effectively. The A1c test is a powerful tool that provides a snapshot of your average blood sugar control over the past 2-3 months. This article provides a simple A1c calculator, explains how to interpret your results in terms of Estimated Average Glucose (eAG), and offers a comprehensive guide to help you understand the significance of these measurements.

What is the A1c Test?
The A1c test, also known as the hemoglobin A1c 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 2-3 months. Unlike a single blood glucose reading, which fluctuates throughout the day, the A1c test provides a more stable and reliable overview of your blood sugar control. This makes it an essential tool for diagnosing prediabetes and diabetes, as well as monitoring the effectiveness of diabetes treatment plans.
Why is A1c Important?
- Diagnosis: A1c helps diagnose prediabetes and diabetes.
- Monitoring: It tracks how well your treatment plan is working.
- Prevention: Maintaining healthy A1c levels can help prevent or delay long-term diabetes complications.
- Personalized Care: Provides your doctor with valuable information to tailor your diabetes management plan.
A1c Calculator: Convert A1c to Estimated Average Glucose (eAG)
Use the table below to quickly convert your A1c value to its corresponding Estimated Average Glucose (eAG) value in mg/dL and mmol/L. Knowing your eAG can help you relate your A1c result to your daily blood glucose monitoring.

| 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 |
| 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: These are estimated averages. Individual results may vary. Remember to always discuss your A1c results with your healthcare provider for personalized recommendations.
Understanding Your A1c Results: What is a Normal Range?
The American Diabetes Association (ADA) generally recommends the following A1c goals:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
However, your target A1c goal may be different based on your individual circumstances, such as age, other medical conditions, and risk of hypoglycemia (low blood sugar). Talk to your doctor to determine your ideal A1c target.
Factors That Can Affect A1c Results
While the A1c test is generally reliable, certain factors can affect its accuracy. These include:
- Anemia: Conditions that affect red blood cells, like anemia, can impact A1c results.
- Hemoglobin Variants: Certain hemoglobin variants (e.g., sickle cell trait) can interfere with A1c testing.
- Kidney Disease: Kidney disease can alter A1c levels.
- Pregnancy: A1c targets may be adjusted during pregnancy.
Always inform your doctor about any medical conditions you have that could potentially affect your A1c results. Alternative blood glucose monitoring methods may be considered in such cases.
How to Lower Your A1c
If your A1c levels are above your target range, there are several steps you can take to lower them:
- Diet: Focus on a balanced diet rich in fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and unhealthy fats.
- Exercise: Regular physical activity helps improve insulin sensitivity and lower blood sugar levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Medication: Your doctor may prescribe medication to help lower your blood sugar levels. Take your medications as directed.
- Regular Blood Glucose Monitoring: Check your blood sugar regularly to understand how different foods, activities, and medications affect your levels.
- Stress Management: Stress can raise blood sugar levels. Practice relaxation techniques such as deep breathing, yoga, or meditation.
- Work closely with your healthcare team: Regularly check in with your doctor, diabetes educator, and registered dietitian to monitor your progress and adjust your treatment plan as needed.
The Connection Between A1c and eAG
Estimated Average Glucose (eAG) is another way to represent your A1c results. While A1c is reported as a percentage, eAG is reported in the same units as your daily blood glucose readings (mg/dL or mmol/L). This can make it easier to understand the connection between your overall blood sugar control (A1c) and your daily blood glucose fluctuations. The formula used to calculate eAG is:
- eAG (mg/dL) = (28.7 x A1c) - 46.7
- eAG (mmol/L) = (1.59 x A1c) - 2.59
The A1c calculator table above provides pre-calculated eAG values for common A1c results.

Living Well with Diabetes: The Importance of A1c Management
Managing your A1c levels effectively is a cornerstone of living well with diabetes. By understanding what the A1c test measures, using the A1c calculator to convert your results to eAG, and following the recommendations of your healthcare team, you can take control of your blood sugar levels and reduce your risk of diabetes-related complications. Regular monitoring, healthy lifestyle choices, and consistent communication with your healthcare providers are essential for long-term success.
