From Hemoglobin A1c to eAG: A Simple Conversion Calculator and Guide
Understanding your blood sugar levels is crucial for managing diabetes effectively. Two common measures used by doctors are Hemoglobin A1c (HbA1c) and estimated Average Glucose (eAG). While HbA1c provides a snapshot of your average blood sugar over the past 2-3 months, eAG translates this into a more easily understandable daily average glucose level. This guide provides a simple conversion calculator and an in-depth explanation of both metrics.
What is Hemoglobin A1c (HbA1c)?
Hemoglobin A1c is a blood test that reflects your average blood sugar level over the past two to three months. It measures the percentage of your red blood cells that have glucose attached to them (glycated). A higher HbA1c indicates higher average blood sugar levels. It is the gold standard for assessing long-term glycemic control. Factors that can affect A1c readings include certain medical conditions and hemoglobin variants.
What is Estimated Average Glucose (eAG)?
Estimated Average Glucose (eAG) is a calculated value that represents your average blood sugar level in milligrams per deciliter (mg/dL) over the same period that HbA1c measures. eAG is often considered more relatable because it expresses blood sugar levels in the same units that people with diabetes typically use to monitor their glucose throughout the day.

Why Convert HbA1c to eAG?
Converting HbA1c to eAG offers several benefits:
- Better Understanding: eAG makes it easier for patients to understand their blood sugar control because it uses the same units they are familiar with (mg/dL or mmol/L).
- Improved Communication: Doctors can use eAG to explain blood sugar levels to patients in a way that is more intuitive and less abstract than percentages.
- Goal Setting: eAG helps patients set realistic goals for their daily blood sugar management.
HbA1c to eAG Conversion Calculator
Use the calculator below to quickly convert your HbA1c to eAG:
(Note: Since providing interactive tools is beyond my capability, I will present a conversion table and formula instead. You can find many free online HbA1c to eAG calculators by searching on Google.)
HbA1c to eAG Conversion Formula
The formula to convert HbA1c to eAG (mg/dL) is:
eAG (mg/dL) = (28.7 x HbA1c) - 46.7
To convert HbA1c to eAG (mmol/L), use the following:
eAG (mmol/L) = (1.59 x HbA1c) - 2.59
HbA1c to eAG Conversion Table
The table below provides a quick reference for common HbA1c values and their corresponding eAG values.
| HbA1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6.0 | 126 | 7.0 |
| 6.5 | 140 | 7.8 |
| 7.0 | 154 | 8.6 |
| 7.5 | 169 | 9.4 |
| 8.0 | 183 | 10.2 |
| 8.5 | 197 | 11.0 |
| 9.0 | 212 | 11.8 |
Important Note: This table provides estimates. Actual eAG values can vary slightly.
What is a Healthy HbA1c and eAG Range?
Target HbA1c and eAG values vary depending on individual factors, such as age, type of diabetes, and other health conditions. Generally, the American Diabetes Association (ADA) recommends:
- HbA1c: Less than 7.0%
- eAG: Less than 154 mg/dL (8.6 mmol/L)

It’s crucial to discuss your target range with your healthcare provider to personalize your treatment plan.
Factors Affecting HbA1c and eAG
Several factors can influence your HbA1c and eAG levels, including:
- Medication adherence: Taking diabetes medications as prescribed is vital.
- Diet: Following a healthy, balanced diet is essential for blood sugar control. Focus on low-glycemic foods.
- Exercise: Regular physical activity helps improve insulin sensitivity and lower blood sugar levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Stress: Stress can elevate blood sugar levels. Managing stress through relaxation techniques can be beneficial.
- Illness: Illnesses can impact blood sugar control. Monitor your levels closely during periods of sickness.
- Anemia: Can lead to falsely low HbA1c readings.
- Kidney disease: Can impact HbA1c readings.

- Follow Your Doctor's Recommendations: Adhere to your prescribed medication regimen and attend regular check-ups.
- Adopt a Healthy Eating Plan: Work with a registered dietitian or certified diabetes educator to develop a meal plan that meets your individual needs. Focus on portion control and limiting sugary drinks and processed foods.
- Increase Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week. Find activities you enjoy to make exercise more sustainable.
- Monitor Blood Sugar Regularly: Check your blood sugar as directed by your healthcare provider and keep a record of your results. This will help you identify trends and make informed decisions about your diet and medication.
- Manage Stress: Practice relaxation techniques such as deep breathing, meditation, or yoga to help manage stress.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Poor sleep can negatively impact blood sugar control.
- Stay Hydrated: Drink plenty of water throughout the day.
The Importance of Regular Monitoring and Consultations
Regular monitoring of your HbA1c and eAG, along with frequent consultations with your healthcare provider, are crucial for effective diabetes management. These measures allow for timely adjustments to your treatment plan based on your individual needs and response to therapy. Furthermore, understanding the relationship between HbA1c, eAG, and your overall health empowers you to take an active role in managing your condition. Consistent monitoring and open communication with your medical team are the cornerstones of successful diabetes management.
Conclusion
Understanding the relationship between HbA1c and eAG is a key component of managing diabetes. Using the conversion formula and table, combined with guidance from your healthcare provider, can help you better understand your blood sugar control and make informed decisions about your health. Remember to consistently monitor your blood sugar, follow a healthy lifestyle, and work closely with your healthcare team for optimal diabetes management.
