Our A1c to Blood Sugar Conversion Chart and eAG Calculator
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. One of the key metrics for this is the A1c test, which provides an average of your blood sugar levels over the past 2-3 months. However, A1c results are often presented as a percentage, while people are more familiar with blood sugar levels in mg/dL or mmol/L. This is where an A1c to blood sugar conversion chart and an eAG calculator (estimated Average Glucose) become invaluable tools.

This article will provide a detailed explanation of what A1c is, how it relates to your average blood sugar, and how to use our comprehensive A1c conversion chart and eAG calculator effectively. We’ll also explore the implications of different A1c levels and what actions you can take to achieve better control.
What is A1c?
The A1c test, also known as hemoglobin A1c, HbA1c, or glycated hemoglobin, measures the percentage of your red blood cells that have glucose attached to them. The higher your blood sugar levels have been, the more glucose will attach to your hemoglobin. This test provides a snapshot of your average blood sugar control over the preceding 2-3 months because red blood cells typically live for about that long. Unlike a daily blood sugar reading that reflects a specific moment in time, A1c gives a more comprehensive picture of your long-term blood sugar management.
Why is A1c Important?
- Diabetes Diagnosis: A1c is used to diagnose prediabetes and diabetes. An A1c of 6.5% or higher usually indicates diabetes.
- Monitoring Diabetes Management: It's a primary tool for people with diabetes to monitor how well their treatment plan is working. Regular A1c testing helps healthcare providers adjust medications, diet, or exercise routines as needed.
- Preventing Complications: Maintaining a target A1c level can significantly reduce the risk of long-term complications associated with diabetes, such as nerve damage (neuropathy), kidney disease (nephropathy), eye damage (retinopathy), and cardiovascular issues.
Introducing the eAG: Estimated Average Glucose
The eAG, or estimated average glucose, is a calculated value that translates your A1c percentage into an average blood sugar level. Because A1c is a percentage and daily blood sugar is typically measured in mg/dL (milligrams per deciliter) or mmol/L (millimoles per liter), eAG makes it easier to understand your A1c result in the context of your day-to-day blood sugar monitoring. Think of eAG as the equivalent of looking at your continuous glucose monitor (CGM) averages over a 2-3 month span.
How the eAG is Calculated
The relationship between A1c and average blood sugar is relatively linear. The formula used to estimate the average glucose level in mg/dL from an A1c percentage is:
eAG (mg/dL) = (28.7 x A1c) - 46.7
To convert eAG from mg/dL to mmol/L, you would divide the result by 18.
eAG (mmol/L) = eAG (mg/dL) / 18
Our A1c to blood sugar conversion chart and calculator perform these calculations for you automatically, making it easy to understand your results.

| 5.0% | 97 | 5.4 | Normal |
| 5.5% | 114 | 6.3 | Normal |
| 5.7% | 117 | 6.5 | Prediabetes |

- Choose Your Preferred Unit: Select whether you want the eAG displayed in mg/dL or mmol/L.
- Calculate: Click the "Calculate" button.
- View Results: The calculator will instantly display your estimated average glucose level in your chosen unit.
Interpreting Your A1c and eAG Results
Understanding what your A1c and eAG numbers mean is crucial for effective diabetes management.
- Normal A1c: For individuals without diabetes, an A1c level is typically below 5.7%. This translates to an eAG of less than 114 mg/dL (6.3 mmol/L).
- Prediabetes A1c: An A1c between 5.7% and 6.4% indicates prediabetes, suggesting a higher risk of developing type 2 diabetes. This corresponds to an eAG range of 114-126 mg/dL (6.3-7.0 mmol/L). Lifestyle changes, such as diet and exercise, can often prevent progression to diabetes at this stage.
- Diabetes A1c: An A1c of 6.5% or higher confirms a diagnosis of diabetes. The target A1c for many people with diabetes is below 7.0% (eAG of 154 mg/dL or 8.6 mmol/L), but the specific target should be determined in consultation with your healthcare provider, considering factors like age, overall health, and risk of hypoglycemia.
Factors Affecting A1c Accuracy
It’s important to recognize that certain factors can affect the accuracy of A1c readings.
- Anemia: Conditions affecting red blood cell production, such as anemia, can lead to falsely low A1c results.
- Hemoglobin Variants: Certain hemoglobin variants or hemoglobinopathies (e.g., sickle cell anemia) can interfere with A1c measurements, requiring alternative testing methods.
- Kidney Disease: Kidney disease can sometimes result in inaccurate A1c levels.
- Pregnancy: A1c targets may be different during pregnancy and A1c tests may be less reliable.
In these situations, your doctor may recommend alternative tests to monitor blood sugar control, such as frequent self-monitoring of blood glucose or continuous glucose monitoring (CGM).
Tips for Improving Your A1c Level
If your A1c is higher than your target, here are some strategies to help you improve your blood sugar control:
- Dietary Changes:
- Focus on Whole Foods: Emphasize whole, unprocessed foods like vegetables, fruits, whole grains, and lean proteins.
- Limit Sugary Drinks and Processed Foods: Reduce your intake of sugary sodas, juices, processed snacks, and fast food, as these can cause rapid spikes in blood sugar.
- Carbohydrate Management: Work with a registered dietitian to determine the appropriate amount and type of carbohydrates for your individual needs.
- Regular Exercise:
- Aerobic Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming.
- Strength Training: Incorporate strength training exercises at least twice a week to improve insulin sensitivity and muscle mass.
- Medication Adherence:
- Take Medications as Prescribed: Follow your healthcare provider's instructions carefully regarding your diabetes medications, including timing and dosage.
- Communicate with Your Doctor: If you experience any side effects or have difficulty adhering to your medication regimen, discuss these concerns with your doctor promptly.
- Stress Management:
- Practice Relaxation Techniques: Engage in activities that help reduce stress, such as yoga, meditation, deep breathing exercises, or spending time in nature.
- Prioritize Sleep: Aim for 7-8 hours of quality sleep each night to support overall health and blood sugar control.
- Regular Monitoring:
- Self-Monitoring of Blood Glucose (SMBG): Check your blood sugar levels regularly as directed by your healthcare provider, especially before meals, after meals, and at bedtime.
- Continuous Glucose Monitoring (CGM): Consider using a CGM system, which provides real-time glucose readings and trends, allowing for more proactive diabetes management.
Working with Your Healthcare Provider
It's crucial to partner with your healthcare provider to develop an individualized diabetes management plan that addresses your specific needs and goals. They can help you:
