Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide for Your Results
Understanding your blood sugar levels is crucial for managing diabetes or pre-diabetes. While blood sugar is often measured in mg/dL (milligrams per deciliter) in the United States, many other countries use mmol/L (millimoles per liter). This article provides a straightforward guide on converting between these two units and understanding why this conversion is important for your health.
Why is Converting Blood Sugar Units Important?
Imagine you're traveling abroad, or communicating with healthcare providers who use a different measurement system. Understanding the conversion between mg/dL and mmol/L is essential to accurately interpret blood sugar readings. Being able to perform this conversion helps you:
- Communicate effectively with healthcare professionals regardless of their location.
- Interpret readings from different blood glucose meters that may use varying units.
- Avoid confusion and potential errors in managing your blood sugar levels.
- Understand research and literature related to diabetes which may use either unit.
The Conversion Formula: mg/dL to mmol/L
The conversion between mg/dL and mmol/L is straightforward. Here's the formula:
mmol/L = mg/dL ÷ 18
Simply divide the value in mg/dL by 18 to get the equivalent value in mmol/L.
The Conversion Formula: mmol/L to mg/dL
To convert from mmol/L back to mg/dL, use the inverse formula:
mg/dL = mmol/L x 18

Example Conversions
Let’s work through some practical examples to illustrate the conversion process.
-
Example 1: Your blood sugar reading is 126 mg/dL. To convert this to mmol/L:
mmol/L = 126 mg/dL ÷ 18 = 7 mmol/L

Example 2: Your blood sugar reading is 5.5 mmol/L. To convert this to mg/dL:
mg/dL = 5.5 mmol/L x 18 = 99 mg/dL
Quick Conversion Table
For your convenience, here is a quick conversion table for some common blood sugar levels.
| mg/dL | mmol/L |
|---|---|
| 70 | 3.9 |
| 100 | 5.6 |
| 126 | 7.0 |
| 150 | 8.3 |
| 180 | 10.0 |
| 200 | 11.1 |
Understanding Healthy Blood Sugar Ranges
Knowing your blood sugar levels is only useful if you understand what a healthy range looks like. Here's a general guideline; however, always consult your doctor for personalized targets:
| 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 |
| Prediabetes | 100 to 125 | 5.6 to 6.9 | 140 to 199 | 7.8 to 11.0 |
| Diabetes | 126 or higher | 7.0 or higher | 200 or higher | 11.1 or higher |
- Fasting Blood Sugar: Measured after at least 8 hours of fasting.
- 2-Hour Postprandial: Measured two hours after starting a meal.
These values provide a general understanding. Your healthcare provider may set different targets based on your specific health conditions and treatment plan. It's always best to discuss your blood sugar targets with them.
Tools for Quick Conversion
Several online converters and mobile apps can perform these conversions automatically. A quick search for "mg/dL to mmol/L converter" will yield numerous options. These tools can be very helpful, especially when you need a quick and accurate conversion. Always double-check the results against the formula, especially for medical decisions.
Factors Affecting Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: Carbohydrate intake significantly affects blood sugar.
- Physical Activity: Exercise can help lower blood sugar.
- Medications: Some medications can increase or decrease blood sugar.
- Stress: Stress hormones can raise blood sugar.
- Illness: Illness can affect blood sugar levels.
- Hydration: Dehydration can impact blood sugar readings.
Understanding these factors and working with your healthcare provider to manage them is crucial for maintaining healthy blood sugar control.
Conclusion
Converting between mg/dL and mmol/L is a valuable skill for anyone managing diabetes or pre-diabetes. By understanding the conversion formulas and utilizing available resources, you can accurately interpret blood sugar readings and effectively communicate with healthcare professionals worldwide. Always consult your doctor for personalized advice on managing your blood sugar levels and achieving optimal health.
