Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide for Reading Your Levels
Related reading: Foods That Lower Blood Sugar Amp Help You Manage Glucose
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. However, blood sugar readings are often reported in different units depending on the region and testing method used. The two primary units are milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This guide will provide a clear and straightforward explanation of the conversion between mg/dL and mmol/L, helping you interpret your results accurately.
Why Two Different Units?
The difference stems from various measurement standards. While both units measure blood glucose, mg/dL is more common in the United States, while mmol/L is predominantly used in Canada, Europe, and many other parts of the world. Familiarizing yourself with both units is beneficial if you travel internationally, use different testing devices, or simply want a broader understanding of diabetes management.
The Conversion Formula: mg/dL to mmol/L
The conversion is relatively simple. To convert blood glucose from mg/dL to mmol/L, you divide the mg/dL value by 18.
Formula:

mmol/L = mg/dL ÷ 18
Example:
If your blood sugar reading is 100 mg/dL, the conversion to mmol/L would be:
100 mg/dL ÷ 18 = 5.56 mmol/L
The Conversion Formula: mmol/L to mg/dL
Conversely, to convert from mmol/L to mg/dL, you multiply the mmol/L value by 18.
Formula:
mg/dL = mmol/L × 18
Example:
If your blood sugar reading is 7 mmol/L, the conversion to mg/dL would be:
7 mmol/L × 18 = 126 mg/dL

While the formulas are simple, having a quick reference table can be even more convenient. Here's a table showing some common blood sugar readings and their equivalents in both units:
| mg/dL | mmol/L |
|---|---|
| 70 | 3.9 |
| 90 | 5.0 |
| 100 | 5.6 |
| 120 | 6.7 |
| 140 | 7.8 |
| 160 | 8.9 |
| 180 | 10.0 |
| 200 | 11.1 |
| 250 | 13.9 |
| 300 | 16.7 |
Understanding Target Blood Sugar Ranges
It’s important to know what blood sugar ranges are considered healthy. These ranges can vary based on individual health conditions and doctor recommendations. However, generally accepted target ranges are as follows:
| Condition | mg/dL (Fasting) | mmol/L (Fasting) | mg/dL (2 hours after meal) | mmol/L (2 hours after meal) |
|---|---|---|---|---|
| Normal | Less than 100 | Less than 5.6 | Less than 140 | Less than 7.8 |
| Pre-Diabetes | 100-125 | 5.6-6.9 | 140-199 | 7.8-11.0 |
| Diabetes | 126 or higher | 7.0 or higher | 200 or higher | 11.1 or higher |
Note: These are general guidelines. Always consult your healthcare provider for personalized blood sugar target ranges.
Common Mistakes and Pitfalls
- Rounding Errors: Be mindful of rounding when converting between units, especially when near a threshold for a diagnosis (e.g., pre-diabetes).
- Device Settings: Ensure your blood glucose meter is set to the correct unit. Consult the device manual if unsure.
- Ignoring Individual Factors: Target ranges depend on individual factors like age, other medical conditions, and medications. Do not self-diagnose or self-treat based solely on the conversion and the general ranges mentioned here.
Using Online Conversion Tools
Numerous online tools can help you quickly convert between mg/dL and mmol/L. These tools are especially useful for repeated conversions or when precision is critical. Simply search "mg/dL to mmol/L converter" on any search engine to find readily available options. Make sure the tool is from a reputable source.
When to Seek Medical Advice
Regular blood sugar monitoring is crucial, especially if you have diabetes or are at risk. Consult your doctor if:
- You experience frequent high or low blood sugar readings.
- You're unsure how to interpret your blood glucose results.
- You're making significant changes to your diet or medication.
Conclusion
Understanding how to convert between mg/dL and mmol/L is a valuable skill for anyone monitoring their blood sugar. This guide equips you with the knowledge and tools to accurately interpret your results, regardless of the units used. By staying informed and proactive, you can effectively manage your health and work collaboratively with your healthcare team. Always remember that accurate monitoring and informed decisions are key to maintaining healthy blood glucose levels.
