A1c to Blood Sugar Conversion Chart & eAG Calculator Explained
Understanding the relationship between A1c levels and blood sugar is crucial for individuals managing diabetes or those at risk of developing the condition. This article breaks down the A1c to blood sugar conversion, provides a handy A1c to blood sugar chart, and explains how the eAG (estimated Average Glucose) calculator works. We'll cover everything you need to know to effectively monitor and manage your blood glucose levels.
What is A1c and Why is it Important?
The A1c test, also known as the Hemoglobin A1c test, measures your average blood sugar level over the past 2-3 months. Unlike a regular blood glucose test that provides a snapshot of your current blood sugar, the A1c test gives a broader picture of your blood sugar control over time.
This is because glucose in the bloodstream binds to hemoglobin, the protein in red blood cells that carries oxygen. The higher your blood sugar levels, the more glucose binds to hemoglobin. The A1c test measures the percentage of hemoglobin that has glucose attached.
Why is A1c Important?
- Long-Term Glucose Control: It provides an average of your blood sugar levels over several months.
- Diabetes Management: It helps healthcare providers monitor how well a diabetes treatment plan is working.
- Diagnosis of Prediabetes and Diabetes: A1c can be used to diagnose prediabetes (A1c between 5.7% and 6.4%) and diabetes (A1c of 6.5% or higher).
- Risk Assessment: It helps assess the risk of developing diabetes-related complications.
Understanding the A1c to Blood Sugar Conversion
The A1c to blood sugar conversion allows you to translate your A1c percentage into an estimated Average Glucose (eAG) reading, measured in mg/dL or mmol/L. This is useful because most people are familiar with daily blood sugar readings from their glucose meter.
The relationship between A1c and average blood glucose is linear, meaning that as A1c increases, so does your average blood sugar level. However, this is an estimate and individual results can vary slightly. Factors like anemia, certain hemoglobinopathies, and ethnicity can affect the accuracy of the A1c test.
A1c to Blood Sugar Conversion Chart
Here's a common A1c to blood sugar conversion chart that shows the relationship between A1c, eAG (mg/dL), and eAG (mmol/L):
| 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 |

Using an eAG Calculator
An eAG calculator simplifies the A1c to blood sugar conversion. These calculators use a formula to estimate your average blood glucose based on your A1c value. There are many online eAG calculators available, including those provided by the American Diabetes Association and various medical websites.

How to Use an eAG Calculator:
- Find a Reliable Calculator: Use a calculator from a reputable source.
- Enter Your A1c Value: Input your A1c percentage into the designated field.
- View the Results: The calculator will display your estimated average glucose in mg/dL and/or mmol/L.
Formula for eAG Calculation:
The formula used for eAG calculation is:

- eAG (mg/dL) = (28.7 x A1c) - 46.7
- eAG (mmol/L) = (1.59 x A1c) - 2.59

Factors Affecting A1c and eAG
Several factors can affect the accuracy of A1c and eAG, including:
- Anemia: Anemia can artificially lower A1c levels.
- Hemoglobinopathies: Conditions like sickle cell anemia and thalassemia can affect A1c accuracy.
- Kidney Disease: Chronic kidney disease can affect red blood cell lifespan and A1c results.
- Pregnancy: Hormonal changes during pregnancy can affect A1c.
- Ethnicity: Some studies suggest that certain ethnicities may have different A1c-glucose relationships.
- Certain Medications: Some medications can interfere with A1c test results.
It's crucial to discuss any medical conditions or medications with your doctor to ensure the A1c test results are interpreted accurately.
Target A1c Levels
The general target A1c level for most adults with diabetes is below 7%. However, target ranges can vary based on individual factors, such as age, other medical conditions, and diabetes treatment plan. It's crucial to work with your healthcare provider to determine the most appropriate A1c target for you.
The American Diabetes Association (ADA) generally recommends the following:
- Non-pregnant adults: A1c < 7%
- Pregnant women with pre-existing diabetes: A1c < 6% to reduce the risk of birth defects.
- Elderly individuals with multiple health problems: Less stringent targets may be appropriate.
Improving Your A1c Levels
If your A1c levels are above your target range, there are several steps you can take to improve them:
- Follow a Healthy Diet: Focus on whole, unprocessed foods, and manage carbohydrate intake. Work with a registered dietitian or diabetes educator to develop an eating plan that fits your needs.
- Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. Regular exercise helps improve insulin sensitivity and lower blood sugar.
- Take Medications as Prescribed: If you are taking medications for diabetes, take them as prescribed by your doctor. Do not change your dose or stop taking medications without consulting your doctor.
- Monitor Your Blood Sugar Regularly: Regularly monitor your blood sugar to see how food, exercise, and medications affect your levels. This can help you and your healthcare team make necessary adjustments to your treatment plan.
- Manage Stress: Stress can affect blood sugar levels. Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Lack of sleep can also affect blood sugar levels. Aim for 7-8 hours of quality sleep per night.
Conclusion
Understanding the A1c to blood sugar conversion, utilizing an eAG calculator, and working with your healthcare provider are essential for effectively managing your blood sugar levels. Regularly monitoring your A1c, following a healthy lifestyle, and adhering to your prescribed treatment plan can help you achieve your target A1c and reduce the risk of diabetes-related complications. Remember that the A1c is an estimate, and individual results may vary, so personalized management is key.
