A1c to Blood Sugar Conversion: Use Our Simple Chart and Calculator
Understanding the relationship between A1c levels and blood sugar levels is crucial for managing diabetes effectively. Your A1c test gives you an average of your blood sugar over the past 2-3 months, while a finger-prick blood sugar test gives you a reading at a single point in time. This article provides a straightforward guide to converting your A1c to an estimated average glucose (eAG), along with a simple conversion chart and a handy calculator.
What is A1c and Why is it Important?
The A1c test, also known as the hemoglobin A1c test, measures the percentage of your red blood cells that have glucose attached to them. It's a key indicator of how well your blood sugar has been controlled over the long term. Unlike a daily blood glucose test that shows your blood sugar at a specific moment, the A1c test provides a broader picture.
Why is this important? Because consistently high blood sugar levels can lead to serious complications, including:
- Heart disease
- Kidney disease
- Nerve damage
- Vision loss
Regular A1c testing helps you and your healthcare provider make informed decisions about your diabetes management plan, including medication adjustments, diet changes, and exercise routines.
Understanding the A1c to eAG Conversion
The estimated Average Glucose (eAG) provides a clearer picture of your average blood sugar level in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). By converting your A1c to eAG, you can directly compare it to the blood sugar readings you take at home.
The relationship between A1c and eAG is generally linear. This means that a higher A1c corresponds to a higher eAG. The equation commonly used for this conversion is:
eAG (mg/dL) = (28.7 x A1c) - 46.7

So, if your A1c is 7%, your estimated average glucose would be:
(28.7 x 7) - 46.7 = 154.2 mg/dL (approximately)

This chart provides a quick reference for converting A1c levels to estimated average glucose (eAG):
| 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 |
| 10.5 | 255 | 14.2 |
| 11.0 | 269 | 15.0 |
| 11.5 | 283 | 15.8 |
| 12.0 | 298 | 16.6 |
Note: These are approximate values, and individual results may vary.
A1c to Blood Sugar Calculator
For a more precise conversion, you can use an online A1c to blood sugar calculator. These calculators automatically apply the formula to determine your eAG based on your A1c result. Simply enter your A1c percentage, and the calculator will provide your estimated average glucose level in mg/dL and mmol/L. There are many free and reliable calculators available online - just search "A1c to eAG calculator" on your favorite search engine.
What is a Target A1c Level?
The target A1c level for most adults with diabetes is below 7%. However, your individual target may vary depending on factors such as:
- Age
- Overall health
- Type of diabetes
- Risk of hypoglycemia (low blood sugar)
Your healthcare provider will determine the most appropriate target A1c for you. It's essential to discuss your A1c results and any necessary adjustments to your diabetes management plan with your doctor or diabetes educator. Maintaining optimal blood sugar control is the key to preventing long-term complications and improving your overall quality of life.

Factors That Can Affect A1c Results
While the A1c test is generally accurate, certain factors can influence the results:

- Anemia: Conditions that affect red blood cell production, such as anemia, can impact A1c levels.
- Hemoglobin variants: Certain hemoglobin variants can interfere with the A1c assay, leading to falsely high or low results.
- Kidney disease: Severe kidney disease can affect the accuracy of A1c testing.
- Pregnancy: A1c levels may be slightly lower during pregnancy.
If you have any of these conditions, your healthcare provider may use alternative methods to monitor your blood sugar control, such as fructosamine testing or continuous glucose monitoring.
The Importance of Regular Monitoring and Management
Understanding your A1c to blood sugar conversion is just one piece of the puzzle in managing your diabetes. It's crucial to:
- Monitor your blood sugar regularly: Check your blood sugar levels at home as directed by your healthcare provider.
- Follow a healthy diet: Focus on whole, unprocessed foods, and limit sugary drinks and refined carbohydrates.
- Engage in regular physical activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Take your medications as prescribed: Adhere to your medication schedule and dosage.
- Attend regular checkups: See your healthcare provider regularly for A1c testing, foot exams, and other necessary screenings.
By actively participating in your diabetes care and understanding the relationship between A1c levels and blood sugar, you can take control of your health and minimize the risk of long-term complications. This includes making good use of tools, like our conversion chart and calculator!
