From A1c to Blood Sugar: A Simple Conversion Calculator and Chart
Understanding your A1c and blood sugar levels is crucial for managing diabetes effectively. Many people with diabetes monitor their blood sugar levels daily and their A1c levels a few times a year. But what does that A1c number actually mean in terms of average blood sugar? This article will demystify the relationship between A1c and blood sugar, providing you with a handy conversion chart and explaining how to use it. We'll also cover the importance of these numbers in managing your health.
What is A1c?
The A1c test (also known as glycated hemoglobin test) provides an average measure of your blood sugar control over the past 2-3 months. It reflects the percentage of your hemoglobin (a protein in red blood cells that carries oxygen) that is coated with sugar (glucose). The higher your blood sugar levels over time, the more hemoglobin will be glycated, and the higher your A1c level will be.

Why is this important? A high A1c indicates prolonged high blood sugar, which can lead to long-term complications of diabetes, such as nerve damage (neuropathy), kidney damage (nephropathy), eye damage (retinopathy), and cardiovascular disease.
What is Blood Sugar (Glucose)?
Blood sugar, or glucose, is the main type of sugar in your blood. It comes from the food you eat and is your body's primary source of energy. Blood sugar levels fluctuate throughout the day, depending on when you eat, how much you eat, and how active you are.
Regularly monitoring your blood sugar levels (using a glucose meter) allows you to see how different factors affect your glucose and helps you make informed decisions about diet, exercise, and medication.
The Relationship Between A1c and Blood Sugar

A1c and average blood sugar are directly related. While A1c provides a longer-term view, your blood sugar readings offer a snapshot of what's happening at any given moment. The A1c test essentially "averages" your blood sugar over a period of months, providing a broader picture of your glycemic control.
Generally, the higher your A1c, the higher your average blood sugar levels. Understanding this connection helps you translate your A1c result into a daily blood sugar target that you can actively manage.
A1c to Average Blood Sugar Conversion Chart
Here's a chart converting A1c levels to estimated average glucose (eAG) in mg/dL and mmol/L. Remember that this chart provides estimates; individual results can vary.
A1c (%) | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (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 | 14.9 |
11.5 | 283 | 15.7 |
12.0 | 298 | 16.5 |
How to Use the Conversion Chart
- Locate Your A1c: Find your A1c result in the first column.
- Find Your Estimated Average Glucose: Look across the row to find your estimated average glucose (eAG) in either mg/dL or mmol/L (depending on the unit your doctor uses).

Example: If your A1c is 7.0%, your estimated average blood sugar is 154 mg/dL (or 8.6 mmol/L).
Factors That Can Affect A1c Results
It's important to note that the A1c test is not perfect, and certain factors can affect its accuracy:
- Anemia: Conditions like anemia can falsely lower your A1c results.
- Hemoglobin Variants: Certain hemoglobin variants can interfere with the A1c test.
- Kidney Disease: Kidney disease can also affect A1c accuracy.
- Pregnancy: A1c levels may be lower during pregnancy.
Always discuss your A1c results with your healthcare provider to interpret them correctly in the context of your individual health situation.
A1c Goals for People with Diabetes
The American Diabetes Association (ADA) generally recommends an A1c goal of less than 7.0% for most non-pregnant adults with diabetes. However, your target A1c level may be different depending on factors such as:
- Your age
- Your overall health
- The type of diabetes you have
- The presence of other medical conditions
- Your risk of hypoglycemia (low blood sugar)
Your doctor will work with you to determine the A1c goal that is right for you. Achieving your A1c goal helps reduce the risk of diabetes-related complications.
Strategies for Lowering A1c
If your A1c is higher than your target, there are several strategies you can implement, under the guidance of your healthcare team:

- Diet: Focus on a healthy eating plan that includes plenty of fruits, vegetables, and whole grains. Limit processed foods, sugary drinks, and excessive carbohydrates.
- Exercise: Regular physical activity helps improve insulin sensitivity and lowers blood sugar. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Medication: If diet and exercise alone are not enough to achieve your A1c goal, your doctor may prescribe diabetes medications.
- Regular Monitoring: Consistently monitor your blood sugar levels and track your results to identify patterns and adjust your treatment plan accordingly.
The Importance of Working with Your Healthcare Team
Managing diabetes effectively requires a team approach. Regular check-ups with your doctor, endocrinologist, certified diabetes educator (CDE), and registered dietitian are crucial for optimizing your blood sugar control and preventing complications. They can provide personalized guidance on diet, exercise, medication, and blood sugar monitoring techniques. Don't hesitate to ask questions and voice any concerns you may have about your diabetes management plan. Your healthcare team is there to support you every step of the way.
By understanding the relationship between A1c and blood sugar levels, using the conversion chart provided, and working closely with your healthcare team, you can take proactive steps to manage your diabetes and live a healthier life. Remember that consistent effort and informed decisions are key to achieving optimal glycemic control.
