A1c to Blood Sugar Conversion Chart & Calculator (eAG Explained)
Understanding the relationship between A1c levels and average blood sugar, or estimated Average Glucose (eAG), is vital for effective diabetes management. This article will provide a comprehensive A1c to blood sugar conversion chart, explain how to use an A1c calculator, and delve into the significance of eAG in monitoring blood glucose control. We’ll cover everything you need to know to interpret your A1c results and make informed decisions about your health.

The A1c test, also known as glycated hemoglobin, measures your average blood sugar level over the past 2-3 months. Unlike a regular blood glucose test that only shows your sugar level at a specific moment, A1c gives a broader picture of your blood sugar control. This test is essential for diagnosing diabetes and prediabetes, as well as for monitoring how well your diabetes treatment plan is working. A lower A1c percentage generally indicates better blood sugar control, reducing the risk of long-term complications associated with diabetes, such as nerve damage, kidney disease, and heart disease. Regularly monitoring your A1c levels allows healthcare professionals to make timely adjustments to your medication, diet, or exercise regimen.
Understanding Estimated Average Glucose (eAG)
Estimated Average Glucose (eAG) is an estimate of your average blood sugar level, calculated from your A1c result. It's expressed in the same units as your daily blood sugar readings, such as mg/dL or mmol/L, making it easier to understand and relate to your daily glucose monitoring. For many individuals with diabetes, seeing their A1c converted into an eAG provides a more intuitive grasp of their overall blood sugar control. For example, an A1c of 7% translates to an approximate average blood sugar level (eAG) of 154 mg/dL. Understanding your eAG allows you to better align your lifestyle choices and medication adherence with your target blood sugar range, improving your overall diabetes management.
A1c to Blood Sugar Conversion Chart
Here’s a detailed A1c to blood sugar conversion chart that shows the relationship between A1c percentages and corresponding eAG values. This chart uses the generally accepted conversion formula.
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 5.0 | 97 | 5.4 |
| 5.5 | 114 | 6.3 |
| 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 | 14.9 |
| 11.5 | 283 | 15.7 |
| 12.0 | 298 | 16.5 |
Note: These are approximate values. Individual results may vary.
How to Use an A1c Calculator
An A1c calculator is a useful tool to convert your A1c result to eAG (and vice versa). You can easily find numerous online A1c calculators by simply searching on Google. These calculators typically require you to input your A1c percentage, and then they automatically calculate the corresponding eAG value in either mg/dL or mmol/L. Using an A1c to eAG calculator allows you to quickly understand your average blood sugar level in a format that aligns with your daily blood glucose readings. Keep in mind that these calculations are estimates and should be used as a guide, not a substitute for medical advice. Consulting with your healthcare provider is always crucial for personalized insights and guidance.
The formula used to calculate eAG (mg/dL) from A1c is: eAG = (28.7 x A1c) - 46.7
The formula used to calculate eAG (mmol/L) from A1c is: eAG = (1.59 x A1c) - 2.59

Target A1c Levels for People with Diabetes
The general target A1c level for most adults with diabetes is below 7%. However, the specific target A1c can vary depending on individual factors such as age, other health conditions, diabetes duration, and risk of hypoglycemia (low blood sugar). Your healthcare provider will determine your personalized A1c target based on your unique health profile. For some individuals, a slightly higher A1c target may be acceptable to minimize the risk of hypoglycemia, while others might benefit from a stricter A1c target to reduce the risk of diabetes-related complications. Regular discussions with your healthcare team will ensure that your A1c target is appropriate for your needs.
Factors That Can Affect A1c Results
Several factors can influence A1c results and may lead to inaccurate readings. These factors include:
- Anemia: Iron deficiency anemia or other types of anemia can falsely lower A1c levels.
- Hemoglobinopathies: Conditions like sickle cell anemia or thalassemia can interfere with A1c measurement.
- Kidney Disease: Chronic kidney disease can affect A1c results.
- Pregnancy: Pregnancy can impact A1c levels due to changes in red blood cell turnover.
- Certain Medications: Some medications can interfere with A1c test results.

If any of these conditions apply to you, it's important to discuss them with your healthcare provider. Alternative methods of monitoring blood sugar, such as continuous glucose monitoring (CGM), might be considered to provide a more accurate assessment of your glucose control.
Tips for Lowering Your A1c
Lowering your A1c is crucial for managing diabetes and preventing complications. Here are some effective tips:
- Follow a Healthy Diet: Focus on balanced meals with plenty of fruits, vegetables, lean protein, and whole grains. Limit processed foods, sugary drinks, and high-fat foods.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, along with strength training exercises.
- Monitor Blood Sugar Regularly: Use a glucose meter to check your blood sugar levels as directed by your healthcare provider. This helps you understand how different foods and activities affect your glucose levels.
- Adhere to Medication: Take your diabetes medications as prescribed by your doctor.
- Stress Management: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Regular Check-ups: Visit your healthcare provider regularly for A1c tests and to discuss any concerns or adjustments to your treatment plan.
- Stay Hydrated: Drink plenty of water throughout the day to help regulate blood sugar levels.
The Importance of Regular A1c Testing
Regular A1c testing is an essential component of diabetes management. The frequency of testing depends on your individual circumstances, such as the type of diabetes you have, how well-controlled your blood sugar levels are, and any changes to your treatment plan. Generally, A1c testing is recommended:
- At least twice a year if you have stable blood sugar levels and are meeting your treatment goals.
- Every three months if your blood sugar levels are not well-controlled or if there have been changes to your treatment plan.
Consistent A1c monitoring allows you and your healthcare team to track your progress, make informed decisions about your diabetes management, and minimize the risk of long-term complications.
Conclusion
Understanding the relationship between A1c levels and estimated Average Glucose (eAG) is vital for effective diabetes management. Using an A1c to blood sugar conversion chart or an A1c calculator can help you interpret your A1c results and better understand your average blood sugar levels. Remember to consult with your healthcare provider to establish a personalized A1c target and develop a comprehensive diabetes management plan. Consistent monitoring, a healthy lifestyle, and adherence to your prescribed treatment will help you achieve optimal blood sugar control and improve your overall health.
