A1c to eAG Conversion Chart: Instantly Translate Your A1c to Average Blood Sugar
Understanding your A1c level is crucial for managing diabetes and prediabetes. However, many people find it easier to relate to their average blood glucose (also known as eAG or estimated Average Glucose) levels. This article provides a comprehensive A1c to eAG conversion chart, explains how the conversion works, and why it's essential for effective diabetes management.
What is A1c?
A1c, also known as glycated hemoglobin, is a blood test that reflects your average blood sugar levels over the past 2-3 months. It measures the percentage of your hemoglobin that has glucose attached to it. A higher A1c indicates higher average blood sugar levels and poorer blood sugar control. Your doctor will use this number to get a good average of your blood sugar levels.
- A normal A1c level is generally below 5.7%.
- An A1c between 5.7% and 6.4% indicates prediabetes.
- An A1c of 6.5% or higher indicates diabetes.
What is eAG?
eAG, or estimated Average Glucose, represents the average blood sugar level in milligrams per deciliter (mg/dL) based on your A1c result. eAG is helpful because it translates your A1c percentage into a number that's similar to what you see on your blood glucose meter daily. This allows you to have a better understanding of how well you're controlling your blood sugar over a longer period.
Why Convert A1c to eAG?
Converting your A1c to eAG offers several benefits:
- Improved Understanding: eAG provides a more intuitive understanding of your blood sugar levels, making it easier to relate to your daily readings.
- Better Self-Management: Knowing your eAG can motivate you to make healthier lifestyle choices and manage your diabetes more effectively.
- Effective Communication: eAG can facilitate better communication with your healthcare provider, as it provides a common ground for discussing your blood sugar control.
- Personalized Targets: Based on your eAG and individual health conditions, your doctor can set personalized target ranges for your blood glucose levels.
A1c to eAG Conversion Chart
Here's a detailed A1c to eAG conversion chart to help you translate your A1c into average blood sugar levels:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 5 | 97 | 5.4 |
| 5.5 | 114 | 6.3 |
| 6 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8 | 183 | 10.2 |
| 8.5 | 197 | 10.9 |
| 9 | 212 | 11.8 |
| 9.5 | 226 | 12.6 |
| 10 | 240 | 13.4 |
| 10.5 | 255 | 14.2 |
| 11 | 269 | 14.9 |
| 11.5 | 283 | 15.7 |
| 12 | 298 | 16.5 |
Note: The eAG values in mmol/L are approximate conversions.
How the A1c to eAG Conversion Works
The relationship between A1c and eAG is a linear one, meaning that for every 1% increase in A1c, there is a corresponding increase in eAG. The formula used to estimate Average Glucose from A1c is as follows:

eAG (mg/dL) = (28.7 x A1c) - 46.7

For example, if your A1c is 7%, your estimated average glucose would be:
eAG = (28.7 x 7) - 46.7 = 200.9 - 46.7 = 154.2 mg/dL
The same formula can be used in metric units (mmol/L) using a conversion factor:
eAG (mmol/L) = (1.59 x A1c) - 2.59
Factors Affecting A1c Accuracy
While the A1c test is generally reliable, certain factors can affect its accuracy. These include:
- Anemia: Can artificially lower A1c levels.
- Hemoglobinopathies: Conditions like sickle cell anemia can interfere with A1c results.
- Kidney Disease: Can impact A1c accuracy.
- Pregnancy: Can affect red blood cell turnover.
- Age: Slightly higher A1c levels can be seen in older adults.
- Ethnicity: Some studies suggest differences in A1c levels among different ethnic groups.
If you have any of these conditions, it's crucial to discuss them with your doctor to determine the best way to monitor your blood sugar levels. In some cases, continuous glucose monitoring (CGM) or frequent self-monitoring of blood glucose may be recommended.
The Role of Regular A1c Testing
Regular A1c testing is crucial for monitoring your blood sugar control and adjusting your diabetes management plan as needed. Here are general guidelines for A1c testing:
- People with diabetes: At least twice a year if meeting treatment goals (and have stable blood sugar control), and quarterly (every 3 months) if treatment changes are made or goals are not being met.
- People with prediabetes: At least annually, but more frequently if there is a higher risk of developing diabetes.
- People with normal A1c levels: Every 3 years as part of routine health screening.
Your doctor will advise you on the appropriate frequency of A1c testing based on your individual health status.
Managing Blood Sugar Levels: Lifestyle Strategies
Beyond knowing your A1c and eAG, it's essential to adopt healthy lifestyle habits to manage your blood sugar effectively. Consider the following strategies:
- Healthy Diet: Follow a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Limit processed foods, sugary drinks, and unhealthy fats. Consult a registered dietitian for personalized guidance.
- Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise each week, such as brisk walking, swimming, or cycling. Include strength training exercises at least twice a week.
- Weight Management: If you are overweight or obese, losing even a small amount of weight (5-10% of your body weight) can significantly improve your blood sugar control.
- Stress Management: Chronic stress can raise blood sugar levels. Practice stress-reducing techniques like meditation, yoga, or deep breathing exercises.
- Medication Adherence: If you are taking medication for diabetes, follow your doctor's instructions carefully. Do not skip doses or adjust your medication without consulting your healthcare provider.
- Regular Monitoring: Monitor your blood sugar regularly using a blood glucose meter or continuous glucose monitor (CGM), as recommended by your doctor. Keep a log of your readings to identify patterns and make necessary adjustments to your treatment plan.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night. Poor sleep can impair insulin sensitivity and increase blood sugar levels.
