A1c to Blood Sugar Conversion Chart & eAG Calculator
Understanding the relationship between your A1c level and your average blood sugar (glucose) is crucial for managing diabetes effectively. The A1c test, also known as the hemoglobin A1c test, provides an average measure of your blood sugar control over the past 2-3 months. It's a valuable tool, but translating that number into a more familiar blood sugar reading can be helpful. This article provides a comprehensive A1c to blood sugar conversion chart and explains how to use the eAG (estimated average glucose) calculator.
What is A1c and Why is it Important?
The A1c test measures the percentage of your red blood cells that have glucose attached to them. Higher A1c levels indicate poorer blood sugar control and a greater risk of diabetes complications. Unlike a single blood sugar reading, the A1c offers a broader view of your glucose levels over time.
Regular A1c testing is vital because:
- Long-term Assessment: It provides a long-term perspective on blood sugar control.
- Treatment Adjustments: Helps your healthcare provider adjust your diabetes treatment plan.
- Risk Reduction: Maintaining a target A1c level reduces the risk of complications like nerve damage, kidney disease, and heart disease.
- Early Detection: It can also identify prediabetes, allowing for lifestyle changes to prevent the onset of type 2 diabetes.
A1c to eAG Conversion Chart
The following chart shows the relationship between A1c levels and estimated average glucose (eAG) levels. The eAG is calculated using a formula that converts A1c to a reading that is closer to what you would see on a glucose meter.
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: These are estimated average glucose levels. Actual blood sugar levels can vary.
How to Use the eAG Calculator
The eAG calculator helps you convert your A1c value into an estimated average glucose level. There are several online calculators available that you can use. To use a calculator:
- Enter your A1c value into the calculator.
- Press "Calculate" or the equivalent button.
- The calculator will display your eAG in mg/dL and mmol/L.
The formula used for conversion is:
- eAG (mg/dL) = (28.7 x A1c) - 46.7
- eAG (mmol/L) = (1.59 x A1c) - 2.59
Example:
If your A1c is 7%, the eAG would be:
- eAG (mg/dL) = (28.7 x 7) - 46.7 = 154.2 mg/dL (approximately 154 mg/dL)
- eAG (mmol/L) = (1.59 x 7) - 2.59 = 8.54 mmol/L (approximately 8.6 mmol/L)
Factors That Can Affect A1c Results
It's important to note that certain factors can affect A1c results, leading to inaccurate interpretations. These include:
- Anemia: Certain types of anemia can falsely lower or raise A1c.
- Hemoglobin Variants: Some hemoglobin variants, more common in certain ethnic groups, can interfere with the A1c test.
- Kidney Disease: Kidney disease can affect the lifespan of red blood cells, impacting A1c results.
- Pregnancy: Pregnancy can also influence A1c values.
If any of these conditions apply to you, discuss with your doctor whether alternative tests, like frequent blood glucose monitoring, might be necessary.

Target A1c Levels

The target A1c level for most adults with diabetes is generally below 7%. However, this target can vary depending on individual circumstances, such as age, other medical conditions, and risk of hypoglycemia (low blood sugar). Your healthcare provider will determine the most appropriate target A1c level for you.
Here's a general guideline:
- Non-diabetic: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
Remember to always consult with your doctor for personalized advice and treatment plans.
Tips for Lowering Your A1c
If your A1c is above your target range, there are several steps you can take to lower it:

- Follow Your Meal Plan: Work with a registered dietitian to create a meal plan that is tailored to your needs and preferences. Focus on balanced meals with appropriate portion sizes. Pay attention to carbohydrate intake.
- 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 levels.
- Monitor Your Blood Sugar Regularly: Frequent blood glucose monitoring helps you understand how your body responds to different foods, activities, and medications.
- Take Medications as Prescribed: Adhere to your prescribed medication regimen. If you have any concerns or side effects, discuss them with your doctor.
- Manage Stress: Stress can affect blood sugar levels. Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Poor sleep can affect blood sugar control.
- Regular Doctor Visits: Attend scheduled appointments with your healthcare team, including your endocrinologist, primary care physician, and certified diabetes educator.

While the A1c test provides a valuable overview, regular blood glucose monitoring is also crucial. It allows you to see how your blood sugar levels fluctuate throughout the day and how they are affected by meals, exercise, stress, and medications. The information gained from regular monitoring can help you make informed decisions about your diabetes management.
Benefit of Regular Blood Glucose Monitoring | Description |
---|---|
Immediate Feedback | Provides real-time data on **blood sugar levels**, allowing for immediate adjustments to diet or activity. |
Pattern Recognition | Helps identify patterns and trends in **blood sugar levels** over time, aiding in better diabetes management. |
Medication Adjustment | Facilitates informed discussions with healthcare providers about medication dosages and adjustments. |
Hypoglycemia Prevention | Assists in detecting and preventing episodes of hypoglycemia (low blood sugar). |
Conclusion
Understanding the relationship between your A1c level and your estimated average glucose is an important part of managing diabetes effectively. The A1c to blood sugar conversion chart and the eAG calculator provide valuable tools for translating A1c values into a more familiar blood sugar reading. While these tools are helpful, they are not a substitute for regular blood glucose monitoring and consultation with your healthcare provider. By working closely with your healthcare team, you can develop a personalized diabetes management plan that helps you achieve your target A1c level and maintain good health. Regularly monitoring your A1c and blood glucose levels, following a healthy lifestyle, and adhering to your treatment plan are essential for preventing diabetes complications and living a long and healthy life.
