Blood Sugar Conversion: How to Read Your mg/dL and mmol/L Results
Understanding your blood sugar levels is essential for managing your health, especially if you have diabetes or are at risk of developing it. Blood sugar is typically measured in two primary units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). Knowing how to interpret and convert between these units is crucial for understanding lab results, using glucose meters, and communicating effectively with your healthcare provider. This article will demystify blood sugar conversion and provide you with the knowledge you need.
Why Are There Different Units for Measuring Blood Sugar?
The use of different units stems from varying measurement standards used in different parts of the world. Mg/dL is predominantly used in the United States, while mmol/L is more common in many other countries, including Canada and most of Europe. Regardless of the unit, the purpose remains the same: to quantify the concentration of glucose in your blood.
Understanding mg/dL (Milligrams per Deciliter)

Mg/dL represents the weight of glucose (in milligrams) in a specific volume of blood (one deciliter, which is 100 milliliters). It's a widely used unit, and many glucose meters sold in the US display readings in mg/dL.
- Normal Range (Fasting): Generally, a fasting blood sugar level between 70 and 99 mg/dL is considered normal for non-diabetics.
- Prediabetes (Fasting): A fasting blood sugar level between 100 and 125 mg/dL often indicates prediabetes.
- Diabetes (Fasting): A fasting blood sugar level of 126 mg/dL or higher, confirmed by a repeat test, typically indicates diabetes.
- After-Meal (Postprandial): Blood sugar levels will naturally rise after eating. For most people without diabetes, a postprandial level will be less than 140 mg/dL two hours after starting a meal.
Understanding mmol/L (Millimoles per Liter)
Mmol/L represents the number of moles of glucose in one liter of blood. This unit is favored in many international scientific and medical communities.
- Normal Range (Fasting): A fasting blood sugar level between 3.9 and 5.5 mmol/L is considered normal for non-diabetics.
- Prediabetes (Fasting): A fasting blood sugar level between 5.6 and 6.9 mmol/L often indicates prediabetes.
- Diabetes (Fasting): A fasting blood sugar level of 7.0 mmol/L or higher, confirmed by a repeat test, typically indicates diabetes.
- After-Meal (Postprandial): A postprandial blood sugar level should ideally be less than 7.8 mmol/L two hours after eating for most people without diabetes.
How to Convert Between mg/dL and mmol/L
The conversion between mg/dL and mmol/L is relatively straightforward:

- To convert mg/dL to mmol/L: Divide the mg/dL value by 18.
- To convert mmol/L to mg/dL: Multiply the mmol/L value by 18.
For example:
- If your blood sugar level is 90 mg/dL, it is equivalent to 90 / 18 = 5 mmol/L.
- If your blood sugar level is 6 mmol/L, it is equivalent to 6 * 18 = 108 mg/dL.
Quick Reference Table for Common Blood Sugar Levels
To simplify the process, here’s a handy reference table for common blood sugar levels in both mg/dL and mmol/L:
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal (Fasting) | 70-99 | 3.9-5.5 |
| Prediabetes (Fasting) | 100-125 | 5.6-6.9 |
| Diabetes (Fasting) | 126+ | 7.0+ |
| Normal (2 hours after eating) | Less than 140 | Less than 7.8 |
Using Online Conversion Tools
Numerous online tools are available to quickly convert between mg/dL and mmol/L. Simply search for "blood sugar converter" or "glucose conversion calculator" to find these resources. They can be particularly useful for quick reference or when dealing with multiple values. These tools are especially helpful in managing your diabetes or understanding potential risks.

Regardless of the units used, consistent blood sugar monitoring is crucial for managing diabetes effectively and preventing complications. Work closely with your healthcare provider to determine the appropriate monitoring schedule and target blood sugar ranges for your individual needs. Regular monitoring helps in making informed decisions about diet, exercise, and medication.
Key Takeaways for Managing Your Blood Sugar
- Know your units: Be aware of whether your readings are in mg/dL or mmol/L.
- Learn the conversion: Understand how to convert between the two units for clear communication with healthcare professionals, especially if traveling internationally or using different devices.
- Consistent Monitoring: Regular monitoring is critical for effective diabetes management.
- Consult Your Doctor: Always discuss your blood sugar readings with your doctor for personalized advice and treatment plans.
- Lifestyle Choices: Remember that diet and exercise have a big impact on your blood sugar levels. Make healthy choices to help keep them in a healthy range.
By understanding the differences between mg/dL and mmol/L and knowing how to convert between them, you can proactively manage your health and make informed decisions regarding your blood sugar levels. Always remember that this information is for educational purposes and shouldn’t replace professional medical advice. Regular consultations with your doctor or a certified diabetes educator are vital for proper diagnosis, treatment, and diabetes management.
