A1C to Blood Sugar Conversion: The Simple Way to Understand eAG
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. The A1C test and estimated average glucose (eAG) are two key metrics used to assess your blood sugar control. This article will explain the A1C to blood sugar conversion, how to understand eAG, and why these measurements are important.
What is A1C?
The A1C test, also known as the hemoglobin A1c test, provides an average of your blood sugar levels over the past 2-3 months. Unlike a fasting blood sugar test, which only measures your blood sugar at one point in time, A1C gives a broader picture of your glucose control. It works by measuring the percentage of your hemoglobin that has glucose attached to it. Higher A1C levels indicate higher average blood sugar levels. It is also referred to as glycated hemoglobin.
Why is A1C Important?
Regular A1C testing helps you and your healthcare provider monitor how well your diabetes management plan is working. Good glycemic control can reduce the risk of long-term complications associated with diabetes, such as:
- Heart disease: High blood sugar can damage blood vessels and increase the risk of heart attack and stroke.
- Kidney disease: Chronic high blood sugar can lead to kidney damage and eventually kidney failure.
- Nerve damage (neuropathy): High blood sugar can damage nerves, leading to pain, numbness, and other problems, particularly in the feet and hands.
- Eye damage (retinopathy): High blood sugar can damage blood vessels in the retina, potentially leading to vision loss.
What is eAG?
Estimated Average Glucose (eAG) is a measurement derived from your A1C result that represents your average blood sugar level over the same 2-3 month period. It's expressed in milligrams per deciliter (mg/dL), the same unit used in daily blood sugar monitoring, making it easier to relate to your everyday glucose readings.
A1C to Blood Sugar Conversion: The Relationship Explained
The A1C to blood sugar conversion is a direct relationship. A higher A1C percentage translates to a higher eAG value. The conversion allows you to understand your A1C result in terms that you may already be familiar with – your daily blood sugar readings. Here’s a common conversion table:
| A1C (%) | eAG (mg/dL) |
|---|---|
| 6% | 126 mg/dL |
| 7% | 154 mg/dL |
| 8% | 183 mg/dL |
| 9% | 212 mg/dL |
| 10% | 240 mg/dL |
| 11% | 269 mg/dL |
| 12% | 298 mg/dL |
This table shows a clear correlation: as the A1C percentage increases, so does the estimated average glucose.
How to Calculate eAG From A1C
While the table above provides a quick reference, you can also calculate eAG from A1C using a simple formula:
eAG (mg/dL) = (28.7 x A1C) - 46.7

For example, if your A1C is 7%, the eAG would be:
eAG = (28.7 x 7) - 46.7 = 153.2 mg/dL (approximately 154 mg/dL as seen in the table)
Interpreting Your A1C and eAG Results
The American Diabetes Association (ADA) generally recommends an A1C target of less than 7% for most non-pregnant adults with diabetes. This translates to an eAG of less than 154 mg/dL. However, your target A1C may vary depending on individual factors, such as age, other health conditions, and risk of hypoglycemia (low blood sugar). Discuss your target A1C and eAG range with your healthcare provider.
Factors That Can Affect A1C Accuracy
While A1C is a valuable tool, certain conditions can affect its accuracy. These include:
- Anemia: Conditions that affect red blood cell production or turnover, such as anemia, can falsely lower or raise A1C results.
- Hemoglobinopathies: Certain genetic conditions affecting hemoglobin, such as sickle cell anemia and thalassemia, can also interfere with A1C testing.
- Kidney disease: Advanced kidney disease can affect A1C results.
- Pregnancy: A1C targets may be different during pregnancy.
If you have any of these conditions, your healthcare provider may use alternative methods to assess your blood sugar control, such as continuous glucose monitoring (CGM) or fructosamine testing.
Improving Your A1C and Lowering Your Blood Sugar
If your A1C is above your target range, there are several steps you can take to improve your blood sugar control:
- Diet: Focus on a balanced diet rich in fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and saturated fats. Work with a registered dietitian for personalized meal planning.
- Exercise: Regular physical activity helps improve insulin sensitivity and lower blood sugar levels. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week.
- Medication: Take your diabetes medications as prescribed by your healthcare provider. Don't skip doses or change your medication regimen without consulting your doctor.
- Blood Sugar Monitoring: Regularly monitor your blood sugar levels to identify patterns and trends. This information can help you make adjustments to your diet, exercise, and medication.
- Stress Management: Chronic stress can raise blood sugar levels. Find healthy ways to manage stress, such as meditation, yoga, or spending time in nature.
- Sleep: Aim for 7-8 hours of quality sleep each night. Sleep deprivation can affect blood sugar control.
The Role of Continuous Glucose Monitoring (CGM)

Continuous Glucose Monitoring (CGM) devices provide real-time glucose readings throughout the day and night. They can be particularly helpful for identifying trends and patterns that may not be apparent with traditional blood sugar monitoring. CGM can also provide valuable insights into how your blood sugar responds to food, exercise, and medication. The readings can help with managing your overall blood glucose levels.

Understanding your A1C to blood sugar conversion and eAG is essential for managing diabetes effectively. Regular communication with your healthcare provider is crucial for setting realistic goals, adjusting your treatment plan as needed, and addressing any concerns you may have. Together, you can develop a personalized strategy to achieve optimal blood sugar control and reduce your risk of long-term complications. They can help you better understand your A1C result.
