Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide for Your Glucose Readings
Understanding your blood sugar readings is crucial for managing diabetes and maintaining overall health. However, blood glucose levels are measured using different units around the world: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article provides a simple conversion guide and explains why understanding these units is important.
Why the Conversion Matters: mg/dL vs. mmol/L

The unit used to measure blood sugar varies depending on the region. In the United States, mg/dL is the standard unit. In Canada and many European countries, mmol/L is more common. If you're traveling, using different monitors, or consulting medical information from various sources, knowing how to convert between these units is essential. It allows you to accurately interpret your glucose readings and communicate effectively with healthcare professionals regardless of where they are located or the units they use.

- 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.
Let's illustrate with a couple of examples:
- Example 1: If your blood glucose reading is 126 mg/dL, to convert it to mmol/L, you divide 126 by 18, resulting in approximately 7 mmol/L.
- Example 2: If your blood glucose reading is 5.5 mmol/L, to convert it to mg/dL, you multiply 5.5 by 18, resulting in 99 mg/dL.
Quick Conversion Chart
For quick reference, here is a handy blood sugar conversion chart. This chart will save you time and effort, especially when you need to quickly interpret your readings:
| 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 |
Understanding Normal Blood Sugar Ranges
Understanding normal blood sugar ranges in both mg/dL and mmol/L is essential for proactively managing your health. These ranges can vary slightly depending on factors like whether you're fasting, have just eaten, or have specific health conditions such as diabetes. Here's a general overview of typical target ranges:
- Fasting Blood Sugar (Target for most adults with diabetes):
- mg/dL: 80-130 mg/dL
- mmol/L: 4.4-7.2 mmol/L
- Postprandial (2 hours after eating, target for most adults with diabetes):
- mg/dL: Less than 180 mg/dL
- mmol/L: Less than 10.0 mmol/L
- Normal Fasting Blood Sugar (for individuals without diabetes):
- mg/dL: 70-99 mg/dL
- mmol/L: 3.9-5.5 mmol/L
It’s crucial to discuss your individual target ranges with your healthcare provider, as these can vary depending on your specific health status and treatment plan.
Online Conversion Tools
While understanding the conversion formula is helpful, several online tools can quickly convert blood sugar values between mg/dL and mmol/L.

Important Considerations
- Consult Your Healthcare Provider: This guide provides general information. Always consult with your doctor or a certified diabetes educator for personalized advice and to determine the most appropriate target blood glucose ranges for you.
- Monitor Accuracy: Ensure that your glucose meter is properly calibrated and functioning accurately. Regularly compare your meter readings with laboratory results to ensure consistency.
- Consistent Units: Be consistent in the unit of measure you use to track your blood sugar levels. This will prevent confusion and ensure accurate monitoring.
- Hypoglycemia and Hyperglycemia: Be aware of the symptoms of both low (hypoglycemia) and high (hyperglycemia) blood sugar, and know how to respond appropriately.
Conclusion
Knowing how to convert blood sugar readings between mg/dL and mmol/L is a valuable skill for anyone managing diabetes or simply interested in understanding their glucose levels. This simple conversion guide and the provided chart should help you easily interpret your readings, communicate effectively with healthcare professionals, and proactively manage your health.
