Blood Sugar Levels (mg/dL vs mmol/L): A Simple Conversion Guide
Understanding blood sugar levels is crucial for managing diabetes and maintaining overall health. However, blood sugar levels can be measured in different units – milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This guide will provide you with a simple conversion to navigate between these two measurement units effectively.
Why Two Different Units for Blood Sugar?
The difference in units stems from variations in regional practices. While mg/dL is more commonly used in the United States, mmol/L is prevalent in many other countries, including Canada and most of Europe. Regardless of where you are, understanding both measurement systems will help you interpret lab results and communicate with healthcare professionals. Understanding your blood sugar levels is very important, regardless of units.
The Conversion Factor
The key to converting between mg/dL and mmol/L lies in a simple conversion factor:
- To convert mg/dL to mmol/L: Divide mg/dL by 18.
- To convert mmol/L to mg/dL: Multiply mmol/L by 18.
For instance, a blood sugar level of 100 mg/dL is equivalent to 5.55 mmol/L (100 / 18 = 5.55). Conversely, 7 mmol/L is equal to 126 mg/dL (7 x 18 = 126). Using these calculations can allow you to easily track your blood sugar levels.

Here's a table that outlines typical blood sugar ranges, expressed in both mg/dL and mmol/L. Keep in mind that these ranges can vary based on individual circumstances and specific medical advice, so always consult with your healthcare provider for personalized guidance.
| Blood Sugar Level | mg/dL | mmol/L |
|---|---|---|
| Normal (Fasting) | 70-99 | 3.9-5.5 |
| Pre-diabetes (Fasting) | 100-125 | 5.6-6.9 |
| Diabetes (Fasting) | 126 or higher | 7.0 or higher |
| Normal (2 hours after eating) | Less than 140 | Less than 7.8 |
| Diabetes (2 hours after eating) | 200 or higher | 11.1 or higher |
Why is it Important to Know This Conversion?
Being able to convert between mg/dL and mmol/L is beneficial for several reasons:
- International Travel: If you travel to countries where mmol/L is used, you'll be able to understand readings from local healthcare providers or devices.
- Sharing Information with Doctors from Different Regions: If you are seeking medical advice from doctors who practice in different regions with varying standards.
- Using International Resources: Many online resources, research papers, and international diabetes guidelines may use mmol/L. Being able to convert these figures makes this information accessible.
- Using Different Glucose Meters: Although most meters allow you to select your preferred unit, understanding the conversion will help if you are switching between devices that use different units by default.
Practical Tips for Managing Your Blood Sugar

Common Misconceptions
Let's address some common misconceptions about blood sugar levels:
- Myth: "As long as my blood sugar is within the normal range sometimes, I don't need to worry." Fact: Maintaining consistent levels within the target range is more critical than occasional readings.
- Myth: "I can rely solely on how I feel to determine if my blood sugar is high or low." Fact: Many people do not experience noticeable symptoms even with significantly elevated or reduced levels, making regular monitoring essential.
- Myth: "All carbohydrates are bad for blood sugar." Fact: Complex carbohydrates with high fiber content affect blood sugar differently and more gradually than simple, refined carbs.
Conclusion
Being able to convert between mg/dL and mmol/L for blood sugar levels is a valuable skill for anyone managing diabetes or concerned about their glucose control. Using the simple conversion factor of 18, you can easily switch between these units, helping you better understand lab results and communicate effectively with healthcare professionals, no matter where you are. Remember, consistency and professional guidance are key to effectively manage your blood sugar and overall health.
