A1c to Blood Sugar Conversion Chart Explained (Plus eAG Calculator)
Understanding the relationship between A1c and blood sugar levels is critical for managing diabetes and maintaining overall health. This article provides a detailed breakdown of the A1c to blood sugar conversion, offering a helpful chart and explaining how to use an estimated average glucose (eAG) calculator. Whether you're newly diagnosed or a long-time diabetes warrior, this guide will help you interpret your A1c results with confidence.
What is A1c?
The A1c test, also known as the hemoglobin A1c test, provides an average of your blood sugar control over the past 2-3 months. It measures the percentage of your red blood cells that have glucose attached to them. Unlike a daily blood sugar test which gives you a snapshot in time, A1c offers a broader picture of your glucose control. Doctors use the A1c test to diagnose type 1 and type 2 diabetes, as well as to monitor how well someone with diabetes is managing their blood sugar.
Why is Understanding the A1c to Blood Sugar Conversion Important?
Knowing how to convert your A1c to average blood sugar levels is essential for several reasons:
- Better Understanding of Results: It helps you grasp what your A1c number means in terms of your day-to-day blood sugar levels.
- Improved Diabetes Management: Enables you to make informed decisions about diet, exercise, and medication.
- Motivation and Goal Setting: Provides a tangible link between lifestyle changes and A1c improvements.
- Doctor-Patient Communication: Facilitates more meaningful conversations with your healthcare provider about your diabetes management plan.
A1c to Blood Sugar Conversion Chart
The following chart provides a common A1c to blood sugar conversion:
| A1c (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (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 |
Please note: This is a general conversion chart. Individual results may vary.
Understanding Estimated Average Glucose (eAG)
The estimated average glucose (eAG) is a calculation derived from your A1c result. It provides an estimated average blood sugar level over the same 2-3 month period that the A1c test covers. Expressed in the same units as daily blood sugar readings (mg/dL or mmol/L), the eAG makes it easier for many people to understand and relate to their A1c results.
How to Use an eAG Calculator
Several online eAG calculators are available. They require you to input your A1c value, and they then convert it into an estimated average glucose reading.
Here's a simple way to manually calculate eAG (in mg/dL):
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 (approximately)

What is a Target A1c Level?
The target A1c level generally recommended for most adults with diabetes is below 7%. However, individual targets may vary based on age, other health conditions, risk of hypoglycemia, and other factors. It’s essential to discuss your personalized target A1c with your healthcare provider. They can consider your individual circumstances to determine the most appropriate goal for you.
Factors That Can Affect A1c Results
It's important to be aware that certain conditions can affect A1c results, making them either falsely high or falsely low. These include:
- Anemia: Can lead to falsely low A1c readings.
- Hemoglobinopathies: (e.g., sickle cell anemia, thalassemia) can interfere with A1c measurement.
- Kidney Disease: Can affect A1c accuracy.
- Pregnancy: Hormonal changes can influence A1c.
- Certain Medications: Some medications can impact A1c levels.

If you have any of these conditions, discuss with your doctor how they might affect your A1c test interpretation.
Tips for Lowering Your A1c
Lowering your A1c often requires a multifaceted approach, including:
- Dietary Changes: Focus on a balanced diet rich in fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and unhealthy fats. Work with a registered dietitian for personalized meal planning.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. This can help improve insulin sensitivity and lower blood sugar levels.
- Medication Adherence: If you take diabetes medications, take them exactly as prescribed by your doctor.
- Blood Sugar Monitoring: Regularly monitor your blood sugar levels to identify patterns and adjust your treatment plan accordingly.
- Stress Management: Practice stress-reducing techniques such as yoga, meditation, or deep breathing exercises. Stress can significantly impact blood sugar.
- Regular Checkups: Maintain regular checkups with your doctor to monitor your progress and make any necessary adjustments to your treatment plan.
The Takeaway
Understanding the A1c to blood sugar relationship, using an eAG calculator, and adopting healthy lifestyle habits are crucial steps in effectively managing diabetes. Remember to work closely with your healthcare team to develop a personalized diabetes management plan that meets your individual needs. Regular monitoring and adjustments, based on your A1c results and overall health, will empower you to live a healthier and more fulfilling life.
