Blood Sugar Conversion: Understanding mg/dL and mmol/L
Understanding blood sugar levels is crucial for managing diabetes and maintaining overall health. However, blood sugar is measured using different units around the world, primarily milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article breaks down these units and provides a simple guide to blood sugar conversion, allowing you to easily interpret blood sugar readings regardless of the measurement scale.
Why Are There Different Units?
The difference in units stems from regional preferences and measurement systems. In the United States and some other countries, blood sugar levels are typically reported in mg/dL. Conversely, many countries in Europe, Canada, and Asia use mmol/L. While the units differ, they both serve the same purpose: to indicate the concentration of glucose in the blood.
Knowing how to convert between these two units is especially useful when:
- Traveling internationally.
- Interpreting lab results from different regions.
- Communicating with healthcare providers who use a different measurement system.
- Reading research or medical literature that uses a different unit.
Understanding mg/dL (Milligrams per Deciliter)
mg/dL expresses the mass of glucose (in milligrams) present in a specific volume of blood (one deciliter, which is equivalent to 100 milliliters). It is a weight/volume measurement. A reading of 100 mg/dL means there are 100 milligrams of glucose in every deciliter of blood.
Understanding mmol/L (Millimoles per Liter)
mmol/L is a measure of molar concentration. It indicates the number of moles of glucose (a mole being a specific number of molecules) present in a liter of blood. Therefore, mmol/L provides information on the quantity of blood sugar molecules per volume, which may be more informative when evaluating how blood sugar affects certain processes within the body.

The Blood Sugar Conversion Formula: mg/dL to mmol/L and Vice Versa
The blood sugar conversion between mg/dL and mmol/L is based on a fixed factor determined by the molecular weight of glucose:
- mg/dL to mmol/L: Divide the mg/dL value by 18.
- Formula: mmol/L = mg/dL ÷ 18
- mmol/L to mg/dL: Multiply the mmol/L value by 18.
- Formula: mg/dL = mmol/L × 18
For example:
- If your blood sugar is 126 mg/dL, the equivalent mmol/L value is 126 ÷ 18 = 7 mmol/L.
- If your blood sugar is 6 mmol/L, the equivalent mg/dL value is 6 × 18 = 108 mg/dL.
Quick Blood Sugar Conversion Chart (HTML Table Format)
Here is a handy chart for quick reference:
| mg/dL | mmol/L |
|---|---|
| 50 | 2.8 |
| 70 | 3.9 |
| 90 | 5.0 |
| 100 | 5.6 |
| 126 | 7.0 |
| 150 | 8.3 |
| 180 | 10.0 |
| 200 | 11.1 |
| 250 | 13.9 |
| 300 | 16.7 |
Normal Blood Sugar Ranges
It is essential to know the target blood sugar ranges appropriate for your condition and under the guidance of your healthcare provider. However, the following table provides general guidelines for normal ranges in both mg/dL and mmol/L, taken from established medical sources:
| Condition | mg/dL | mmol/L |
|---|---|---|
| Fasting (Normal) | 70-99 | 3.9-5.5 |
| 2-Hour Postprandial (Normal) | Less than 140 | Less than 7.8 |
| Fasting (Diabetes) | 126 or higher | 7.0 or higher |
| 2-Hour Postprandial (Diabetes) | 200 or higher | 11.1 or higher |

Online Blood Sugar Conversion Tools
For convenient blood sugar conversion, many online tools and apps are available. These calculators typically offer accurate and instant conversions, saving you time and effort. Simply enter the value in mg/dL or mmol/L, and the tool will automatically convert it to the other unit. Always double-check the results with a trusted healthcare provider.
Practical Tips for Managing Blood Sugar
Beyond conversion, here are some essential tips for managing blood sugar levels:
- Regular Monitoring: Consistently check your blood sugar levels, especially if you have diabetes.
- Healthy Diet: Eat a balanced diet low in processed foods, sugars, and refined carbohydrates.
- Regular Exercise: Physical activity helps improve insulin sensitivity and lowers blood sugar levels.
- Medication Adherence: Take any prescribed medications as directed by your healthcare provider.
- Hydration: Drink plenty of water to help regulate blood sugar.
- Stress Management: Implement strategies to reduce stress, as stress can impact blood sugar levels.
- Regular Checkups: Schedule regular appointments with your doctor to monitor your health.
Common Misconceptions About Blood Sugar Conversion

One common misconception is that one unit is "better" than the other. Both mg/dL and mmol/L are equally valid; they are simply different ways of expressing the same value. Another misunderstanding involves inaccurately estimating the conversion factor. Remember to use 18 (either dividing or multiplying) for accurate blood sugar conversion. Finally, remember that these conversions are not meant to replace professional medical advice or guidance.
Conclusion
Understanding the difference between mg/dL and mmol/L for blood sugar levels, and how to convert between them, is essential for effective diabetes management and overall health monitoring. By utilizing the formulas, charts, and tips outlined in this article, you can easily interpret blood sugar readings and work effectively with healthcare professionals to maintain optimal health. Always consult with a healthcare provider for personalized advice and treatment plans regarding blood sugar management.
