Your A1c to Blood Sugar Conversion Chart: Decode Your eAG
Understanding your A1c levels is crucial for managing diabetes and prediabetes. The A1c test provides an average of your blood sugar levels over the past 2-3 months, offering a broader picture than daily finger-prick tests. This article will explain the A1c test, how it relates to your estimated average glucose (eAG), and provide a comprehensive A1c to blood sugar conversion chart to help you interpret your results effectively.
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. The higher your blood sugar levels, the more glucose attaches to your hemoglobin. This test doesn’t require fasting and can be done at any time of day, making it a convenient option for both patients and healthcare providers.
- It’s a long-term measure of blood sugar control.
- Results are typically expressed as a percentage.
- It's a standard test for diagnosing prediabetes and diabetes.
Why is A1c Important?
Monitoring your A1c is important because it provides a clearer picture of your overall blood sugar control. Regular monitoring can help:
- Diagnose Diabetes and Prediabetes: An A1c test can determine if you fall into the prediabetic or diabetic range.
- Manage Existing Diabetes: Track how well your treatment plan is working.
- Prevent Complications: Maintaining a healthy A1c level can significantly reduce the risk of long-term complications like kidney disease, nerve damage, and cardiovascular problems.
Understanding eAG (Estimated Average Glucose)
While A1c is reported as a percentage, it can be translated into an estimated average glucose (eAG), which is measured in mg/dL (milligrams per deciliter). The eAG provides a more familiar way to understand your average blood sugar levels. This conversion helps many patients visualize their A1c results in terms of daily blood sugar readings they are used to.

The relationship between A1c and eAG is based on a mathematical equation. The most common formula is:

eAG (mg/dL) = (28.7 x A1c) - 46.7
This formula allows healthcare professionals and individuals to easily convert between A1c percentages and average blood glucose values.
A1c to Blood Sugar Conversion Chart (eAG Table)
Here’s a handy A1c to blood sugar conversion chart to help you understand your results and what they mean in terms of your average glucose levels.
| A1c (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (eAG) mmol/L | Interpretation |
|---|---|---|---|
| 5.0% | 97 mg/dL | 5.4 mmol/L | Normal |
| 5.5% | 114 mg/dL | 6.3 mmol/L | Normal |
| 5.7% | 117 mg/dL | 6.5 mmol/L | Prediabetes |
| 6.0% | 126 mg/dL | 7.0 mmol/L | Prediabetes |
| 6.5% | 140 mg/dL | 7.8 mmol/L | Diabetes |
| 7.0% | 154 mg/dL | 8.6 mmol/L | Diabetes |
| 8.0% | 183 mg/dL | 10.1 mmol/L | Diabetes (Poor Control) |
| 9.0% | 212 mg/dL | 11.8 mmol/L | Diabetes (Poor Control) |
| 10.0% | 240 mg/dL | 13.3 mmol/L | Diabetes (Very Poor Control) |
| 11.0% | 269 mg/dL | 14.9 mmol/L | Diabetes (Very Poor Control) |
| 12.0% | 298 mg/dL | 16.5 mmol/L | Diabetes (Extremely Poor Control) |
Note: The conversion chart provides estimated average glucose values. Actual glucose levels can vary.
Interpreting the Chart
- Normal: An A1c below 5.7% is considered normal.
- Prediabetes: An A1c between 5.7% and 6.4% indicates prediabetes, meaning you’re at a higher risk of developing type 2 diabetes.
- Diabetes: An A1c of 6.5% or higher indicates diabetes.
Understanding these ranges will help you better interpret your A1c results and take appropriate action with the help of your healthcare provider.
Factors That Can Affect A1c Results
While the A1c test is generally reliable, certain factors can influence the results:
- Anemia and Hemoglobin Variants: Certain types of anemia or hemoglobin variants can affect the accuracy of the test.
- Kidney Disease: Kidney disease can sometimes lead to inaccurate A1c readings.
- Ethnicity: Some studies suggest that A1c levels may vary slightly among different ethnic groups.
If you have any of these conditions, discuss with your doctor whether an A1c test is the most accurate way to monitor your blood sugar.
How Often Should You Get Tested?
The frequency of A1c testing depends on several factors:
- Diagnosed with Diabetes: If you have diabetes and your blood sugar is well-controlled, testing twice a year may be sufficient. If your treatment plan has changed or your blood sugar isn’t well-managed, testing every three months is recommended.
- Prediabetes: If you have prediabetes, testing every year is usually sufficient, unless otherwise recommended by your doctor.
- No Diabetes or Prediabetes: Individuals without diabetes or prediabetes typically do not need routine A1c testing. However, if you have risk factors for diabetes (such as a family history, obesity, or sedentary lifestyle), your doctor may recommend occasional testing.
Tips for Lowering Your A1c
If your A1c is higher than the target range, there are several steps you can take to improve your blood sugar control:
- Follow a Healthy Diet: Focus on balanced meals with plenty of fruits, vegetables, and whole grains. Limit sugary drinks and processed foods.
- Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Monitor Your Blood Sugar: Regularly check your blood sugar levels to understand how different foods and activities affect you.
- Take Medications as Prescribed: If you’re on medication for diabetes, take it as directed by your doctor.
- Manage Stress: High stress levels can affect blood sugar. Practice stress-reducing techniques like yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Lack of sleep can affect insulin sensitivity. Aim for 7-8 hours of quality sleep per night.
Working with Your Healthcare Provider
Understanding your A1c results and its correlation with eAG is an important step in managing your health, but it's not a substitute for professional medical advice. Always work closely with your healthcare provider to develop a personalized diabetes management plan that addresses your unique needs and health conditions. They can provide the most accurate interpretation of your test results and help you make informed decisions about your treatment and lifestyle.
