Blood Sugar Conversion: A Simple Guide to mg/dL, mmol/L, and Your A1c
Understanding your blood sugar levels is crucial, especially if you're managing diabetes. Different countries and labs use different units for measuring blood glucose. This guide provides a simple explanation of blood sugar conversion between mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter), and how these measurements relate to your A1c. We'll break down the process, offer helpful conversion tools, and provide context so you can better interpret your results.
Understanding Blood Sugar Measurement Units: mg/dL vs. mmol/L
The two most common units for measuring blood glucose levels are:
- mg/dL (milligrams per deciliter): This unit is primarily used in the United States, Japan, and some other countries. It represents the mass of glucose (in milligrams) present in a specific volume of blood (one deciliter).
- mmol/L (millimoles per liter): This unit is widely used in Canada, Europe, Australia, and other parts of the world. It represents the number of molecules of glucose (in millimoles) present in a specific volume of blood (one liter).
Understanding both units is important because you might encounter either depending on your location or lab results. Knowing how to perform a blood sugar conversion ensures accurate interpretation of your health data.
How to Convert mg/dL to mmol/L and Vice Versa
Converting between mg/dL and mmol/L is straightforward. Here's the formula:
- mg/dL to mmol/L: Divide the mg/dL value by 18. (mmol/L = mg/dL / 18)
- mmol/L to mg/dL: Multiply the mmol/L value by 18. (mg/dL = mmol/L * 18)
For example:
- If your blood sugar level is 100 mg/dL, the equivalent in mmol/L is 100 / 18 = 5.56 mmol/L (approximately).
- If your blood sugar level is 7 mmol/L, the equivalent in mg/dL is 7 * 18 = 126 mg/dL.
Using this simple blood sugar conversion equation will ensure you can accurately interpret your blood sugar numbers regardless of the unit used.
Blood Sugar Level Goals: A Comparison Table
Target blood sugar levels vary depending on individual factors like age, type of diabetes, and overall health. However, general guidelines exist, and it’s useful to see these guidelines expressed in both mg/dL and mmol/L. Always consult with your healthcare provider to determine the optimal range for you.

Here's a table summarizing typical target blood sugar ranges:
| Condition | Target Blood Sugar (mg/dL) | Target Blood Sugar (mmol/L) |
|---|---|---|
| Fasting (Before Breakfast) | 80-130 mg/dL | 4.4-7.2 mmol/L |
| 2 Hours After Meal | Less than 180 mg/dL | Less than 10.0 mmol/L |
This table provides a convenient way to understand blood sugar level goals expressed in both mg/dL and mmol/L. Keep in mind that these are general guidelines; your doctor may recommend different targets.
The A1c Test: Understanding Your Average Blood Sugar
The A1c test (also known as glycated hemoglobin) provides a measure of your average blood sugar levels over the past 2-3 months. It's expressed as a percentage. Understanding the relationship between A1c and average blood sugar (expressed in both mg/dL and mmol/L) can offer a more comprehensive view of your diabetes management.
Here’s how the A1c test correlates to estimated average glucose (eAG) in both units:
| A1c (%) | eAG (mg/dL) | eAG (mmol/L) |
|---|---|---|
| 6% | 126 mg/dL | 7.0 mmol/L |
| 7% | 154 mg/dL | 8.6 mmol/L |
| 8% | 183 mg/dL | 10.2 mmol/L |
| 9% | 212 mg/dL | 11.8 mmol/L |
| 10% | 240 mg/dL | 13.4 mmol/L |
| 11% | 269 mg/dL | 14.9 mmol/L |
| 12% | 298 mg/dL | 16.5 mmol/L |

Maintaining a target A1c level (usually below 7% for most adults with diabetes) is crucial for preventing long-term complications. Monitoring both your blood sugar levels and your A1c provides the most comprehensive view of your glycemic control. Remember to always discuss your A1c results and target range with your doctor.
Practical Tips for Managing Your Blood Sugar
Here are some practical tips to help manage your blood sugar levels:
- Regular Monitoring: Regularly check your blood sugar levels as directed by your healthcare provider. Keep a record of your results to track trends.
- Healthy Diet: Follow a balanced diet that is low in processed foods, sugary drinks, and unhealthy fats. Focus on whole grains, lean protein, fruits, and vegetables.
- Regular Exercise: Engage in regular physical activity to improve insulin sensitivity and lower blood sugar levels. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Medication Adherence: Take your diabetes medications as prescribed by your doctor. Do not skip doses or adjust your medication without consulting your healthcare team.
- Stay Hydrated: Drink plenty of water throughout the day to help regulate blood sugar levels.
- Stress Management: Practice stress-reduction techniques such as meditation, yoga, or deep breathing exercises, as stress can impact blood sugar.
- Regular Check-ups: Schedule regular appointments with your healthcare provider to monitor your diabetes management plan and make necessary adjustments.
By following these tips, you can effectively manage your blood sugar levels and improve your overall health. Understanding blood sugar conversion between mg/dL and mmol/L is just one part of a comprehensive approach to diabetes management. Always consult with your healthcare provider for personalized advice and treatment plans.
