Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide and Chart
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. While blood sugar is commonly measured in mg/dL (milligrams per deciliter) in the United States, other parts of the world use mmol/L (millimoles per liter). This guide will provide a simple way to convert between these two units, along with a handy conversion chart to make the process even easier.
Why the Difference in Units?
The difference in units is primarily due to regional preferences and standardized measurement systems. In the US, mg/dL is the prevailing unit, while mmol/L is more commonly used in countries adhering to the International System of Units (SI). Regardless of the unit used, the important thing is to understand what the numbers mean for your health and to communicate effectively with your healthcare provider.
The Conversion Formula: mg/dL to mmol/L
The conversion from mg/dL to mmol/L is a straightforward calculation. To convert from mg/dL to mmol/L, you divide the mg/dL value by 18. Decoding Your Results The Official Blood Sugar Levels For A Diabetes Diagnosis
Formula: mmol/L = mg/dL ÷ 18
Example: If your blood sugar reading is 100 mg/dL, the equivalent in mmol/L is 100 ÷ 18 = 5.56 mmol/L.
The Conversion Formula: mmol/L to mg/dL
The reverse conversion, from mmol/L to mg/dL, is also a simple calculation. 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 equivalent in mg/dL is 7 × 18 = 126 mg/dL.
Conversion Chart: Quick Reference for Common Blood Sugar Levels
Here's a handy conversion chart for commonly encountered blood sugar levels, allowing for quick and easy reference. Note that you should always consult with your healthcare provider regarding your specific target blood sugar ranges.
mg/dL | mmol/L | General Interpretation |
---|---|---|
70 | 3.9 | Low (Hypoglycemia) |
80 | 4.4 | Normal (Fasting) |
100 | 5.6 | Normal (Fasting) |
126 | 7.0 | Diabetes (Fasting) |
140 | 7.8 | Normal (2 hours after eating) |
180 | 10.0 | Target for many with diabetes (2 hours after eating) |
200 | 11.1 | Diabetes (2 hours after eating) |
Important Note: These are general guidelines. Your target blood sugar range may vary depending on your individual circumstances and treatment plan.

Using Online Conversion Tools
If you prefer not to perform the calculations manually, several online blood sugar conversion tools are available. These tools can instantly convert mg/dL to mmol/L and vice-versa. Simply search for "mg/dL to mmol/L converter" on your preferred search engine. Always double-check the results to ensure accuracy.
Understanding Blood Sugar Levels and Diabetes Management
Understanding and managing your blood sugar is essential for preventing complications associated with diabetes. High blood sugar (hyperglycemia) can lead to long-term health problems such as nerve damage, kidney damage, and heart disease. Low blood sugar (hypoglycemia) can cause symptoms like shakiness, sweating, and confusion, and can be dangerous if left untreated. Regularly monitoring your blood sugar, following a healthy diet, engaging in physical activity, and taking prescribed medications are crucial aspects of diabetes management.
