The A1C Chart Explained: Converting Your A1C to Blood Sugar Levels
Understanding your A1C level is crucial for managing diabetes or prediabetes. This article will break down the A1C chart, explaining how to convert your A1C result into an estimated average blood sugar level (eAG) and what those numbers mean for your health. We'll cover everything from what A1C is to how it compares with daily blood sugar monitoring.
What is A1C and Why is it Important?
A1C, also known as glycated hemoglobin, is a blood test that reflects your average blood sugar levels over the past 2-3 months. Unlike a daily blood sugar reading, which only provides a snapshot in time, A1C gives a broader picture of your blood sugar control. This makes it a powerful tool for diagnosing and managing diabetes.
Think of it like this: daily blood sugar checks are like taking individual snapshots of a landscape, whereas A1C is like getting a satellite image showing the whole area over several months. Understanding your A1C helps you and your healthcare provider assess how well your diabetes treatment plan is working and make necessary adjustments.
Understanding the A1C Chart and eAG
The A1C chart correlates A1C percentages with estimated average glucose (eAG) levels. The eAG is expressed in milligrams per deciliter (mg/dL), the same unit used for daily blood sugar readings. Here's a basic overview; a more detailed table follows below.
- A1C below 5.7%: Normal blood sugar levels
- A1C between 5.7% and 6.4%: Prediabetes
- A1C 6.5% or higher: Diabetes
The higher your A1C percentage, the higher your average blood sugar level. Converting your A1C to eAG provides a more relatable number, similar to what you see on your glucose meter. The formula used for this conversion is: eAG (mg/dL) = (28.7 x A1C) - 46.7.

Below is a more comprehensive A1C conversion chart. Remember this data represents an estimation. Individual results can vary.
| A1C (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (eAG) mmol/L |
|---|---|---|
| 5.0% | 97 mg/dL | 5.4 mmol/L |
| 5.5% | 114 mg/dL | 6.3 mmol/L |
| 6.0% | 126 mg/dL | 7.0 mmol/L |
| 6.5% | 140 mg/dL | 7.8 mmol/L |
| 7.0% | 154 mg/dL | 8.6 mmol/L |
| 7.5% | 169 mg/dL | 9.4 mmol/L |
| 8.0% | 183 mg/dL | 10.2 mmol/L |
| 8.5% | 197 mg/dL | 10.9 mmol/L |
| 9.0% | 212 mg/dL | 11.8 mmol/L |
| 9.5% | 226 mg/dL | 12.6 mmol/L |
| 10.0% | 240 mg/dL | 13.4 mmol/L |
| 10.5% | 255 mg/dL | 14.2 mmol/L |
| 11.0% | 269 mg/dL | 14.9 mmol/L |
| 11.5% | 283 mg/dL | 15.7 mmol/L |
| 12.0% | 298 mg/dL | 16.5 mmol/L |
Important Considerations: These values are estimates. Individual blood sugar control can vary significantly based on factors like diet, exercise, medication, and other health conditions.
How to Interpret Your A1C Results
Once you have your A1C result and have converted it to eAG, you can start interpreting what it means for your health.
- Normal (A1C < 5.7%): Indicates that your average blood sugar levels are within the normal range. Continue to maintain a healthy lifestyle.
- Prediabetes (A1C 5.7% - 6.4%): Means your blood sugar levels are higher than normal, but not high enough to be diagnosed with diabetes. This is a crucial time to make lifestyle changes (diet and exercise) to prevent the progression to type 2 diabetes. Regular monitoring of your A1C levels is also essential.
- Diabetes (A1C ≥ 6.5%): Indicates that you have diabetes. Your doctor will discuss treatment options, which may include lifestyle changes, medication, or insulin therapy. The target A1C for most people with diabetes is below 7%, but this may vary based on individual circumstances.

It's important to note that several factors can affect the accuracy of the A1C test. These include:
- Certain medical conditions: Anemia, kidney disease, and liver disease can affect A1C results.
- Hemoglobin variants: Some genetic variations in hemoglobin can interfere with the A1C test.
- Recent blood loss or transfusions: These can temporarily lower A1C levels.
If you have any of these conditions, your doctor may need to use other methods to assess your blood sugar control.

A1C vs. Daily Blood Sugar Monitoring
While the A1C test provides a long-term view of blood sugar control, daily blood sugar monitoring is still important for day-to-day management. Daily monitoring allows you to see how your blood sugar levels respond to meals, exercise, and medication, enabling you to make immediate adjustments. A1C, on the other hand, helps you assess the overall effectiveness of your management plan. The two work hand-in-hand to provide a complete picture of your blood sugar control.
Lifestyle Changes to Improve Your A1C
If your A1C is above the target range, making lifestyle changes can significantly improve your blood sugar control. Here are some key strategies:
- Healthy Diet: Focus on whole, unprocessed foods, including fruits, vegetables, lean proteins, and whole grains. Limit sugary drinks, processed foods, and saturated fats.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Weight Management: Losing even a small amount of weight can improve insulin sensitivity and lower blood sugar levels.
- Stress Management: Stress can raise blood sugar levels. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Medication Adherence: If you are taking medication for diabetes, it's important to take it as prescribed.
Working with Your Healthcare Provider
The A1C test is a valuable tool, but it's just one piece of the puzzle. It's essential to work closely with your healthcare provider to develop a personalized diabetes management plan that addresses your individual needs and goals. They can help you interpret your A1C results, adjust your medication if necessary, and provide guidance on lifestyle changes. Regular check-ups and open communication with your healthcare provider are crucial for managing diabetes effectively and preventing complications. Don't hesitate to ask questions and express any concerns you may have.
Conclusion
Understanding your A1C level and converting it to an estimated average blood sugar gives you a clearer picture of your overall blood sugar control. Use the A1C chart provided here as a reference and discuss your results with your doctor. By actively managing your diabetes or prediabetes, you can significantly improve your health and well-being. Remember, small, consistent changes can make a big difference in your long-term health outcomes.
