From A1c to eAG: A Simple Conversion Guide and Calculator for Your Blood Sugar
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. Two important measurements used to assess blood sugar control are A1c and estimated Average Glucose (eAG). While they both provide insights into your glucose levels, they do so in different ways. This guide will explain the relationship between A1c and eAG, provide a simple conversion method, and offer a handy calculator to help you translate between the two.
What is A1c?
A1c, also known as hemoglobin A1c or glycated hemoglobin, provides an average picture of your blood sugar control over the past 2-3 months. It 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 be bound to your hemoglobin. This test doesn't require fasting and is a standard tool for diagnosing prediabetes and diabetes, as well as monitoring glucose control in individuals with diagnosed diabetes.
- A normal A1c level is generally below 5.7%.
- An A1c level between 5.7% and 6.4% indicates prediabetes.
- An A1c level of 6.5% or higher indicates diabetes.
What is eAG?
Estimated Average Glucose (eAG), as the name suggests, is an estimate of your average blood sugar levels over a period of time. It's expressed in the same units (mg/dL or mmol/L) that you typically see on your glucose meter when you check your blood sugar at home. Many people find eAG easier to understand than A1c because it provides a more direct representation of their average glucose values. For example, an eAG of 126 mg/dL means that, on average, your blood sugar has been around 126 mg/dL over the past few months.
The Relationship Between A1c and eAG
A1c and eAG are directly related. A higher A1c level corresponds to a higher eAG. The conversion formula is based on a mathematical relationship derived from clinical studies. Understanding this connection allows healthcare professionals and individuals with diabetes to have a more comprehensive view of their glycemic control. Translating your A1c into an easily understandable eAG can enhance your motivation to manage your blood sugar levels effectively.
Converting A1c to eAG: A Simple Formula
While various online calculators are available (and we'll provide one below!), you can also perform a quick estimate using a simple formula. The formula to convert A1c to eAG (in mg/dL) is:
eAG (mg/dL) = (28.7 x A1c) - 46.7
For example, if your A1c is 7%, then:
eAG = (28.7 x 7) - 46.7 = 200.9 - 46.7 = 154.2 mg/dL
Therefore, an A1c of 7% roughly corresponds to an eAG of 154 mg/dL.
A1c to eAG Conversion Chart
The following table provides a quick reference for common A1c to eAG conversions. Keep in mind that these are approximate values.
| A1c (%) | 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 |
| 9.5 | 226 | 12.6 |
| 10.0 | 240 | 13.4 |
Using an A1c to eAG Calculator
For more precise conversions, using an online A1c to eAG calculator is recommended. Many free calculators are available online. Simply enter your A1c value, and the calculator will automatically convert it to eAG in either mg/dL or mmol/L. These calculators use the most accurate conversion formulas available and can be very helpful for managing your diabetes and understanding the implications of your blood sugar tests.

Why Convert A1c to eAG?
There are several reasons why converting A1c to eAG can be beneficial:
- Improved Understanding: eAG is expressed in the same units as your daily glucose readings, making it easier to grasp the average level of your blood sugar.
- Enhanced Motivation: Seeing your A1c translated into eAG can be a powerful motivator to make positive changes to your diet, exercise, and medication adherence.
- Better Communication with Healthcare Providers: You can use your eAG to better understand your healthcare provider’s recommendations and ask more informed questions.
- Personalized Goals: Working with your doctor, you can set personalized eAG goals based on your individual needs and health conditions.

While A1c is a valuable tool, certain factors can affect its accuracy:
- Anemia: Anemia can falsely lower A1c levels.
- Hemoglobin Variants: Certain hemoglobin variants can interfere with A1c test results.
- Kidney Disease: Kidney disease can falsely elevate A1c levels.
- Pregnancy: Pregnancy can affect A1c levels.
- Ethnicity: Studies suggest that A1c levels may vary slightly among different ethnic groups.
