Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide for Your Lab Results
Understanding your blood sugar levels is crucial for managing your health, especially if you have diabetes or are at risk of developing it. Blood sugar readings can be expressed in different units depending on where you are in the world. The two most common units are milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article provides a clear and concise guide to converting blood sugar values between these two units, helping you easily interpret your lab results and monitor your health more effectively.
Why Different Units?
The use of mg/dL and mmol/L for measuring blood sugar stems from varying measurement standards adopted by different regions. The United States predominantly uses mg/dL, while many other countries, including Canada and most of Europe, use mmol/L. Knowing how to convert between these units allows you to:
- Understand lab results from different countries.
- Compare readings across different devices that might display different units.
- Effectively communicate your blood sugar levels to healthcare professionals regardless of their preferred unit.
The Simple Conversion Formula
Converting blood sugar levels from mg/dL to mmol/L is straightforward. You simply divide the mg/dL value by 18.
- Formula: mmol/L = mg/dL ÷ 18
Conversely, to convert from mmol/L to mg/dL, you multiply the mmol/L value by 18.
- Formula: mg/dL = mmol/L × 18
Examples of Conversions
Let's look at some practical examples:
-
Converting 100 mg/dL to mmol/L:
mmol/L = 100 mg/dL ÷ 18 mmol/L = 5.56
Therefore, 100 mg/dL is equal to 5.56 mmol/L.
-
Converting 7 mmol/L to mg/dL:
mg/dL = 7 mmol/L × 18 mg/dL = 126
Therefore, 7 mmol/L is equal to 126 mg/dL.
Reference Ranges and What They Mean
Knowing the conversion is only half the battle. You also need to understand what those numbers mean. Below is a table providing common blood sugar reference ranges in both mg/dL and mmol/L. These ranges are generally accepted guidelines, but your doctor may have specific targets for you based on your individual health conditions.

| Category | mg/dL (Fasting) | mmol/L (Fasting) |
|---|---|---|
| Normal | 70-99 | 3.9-5.5 |
| Prediabetes | 100-125 | 5.6-6.9 |
| Diabetes | 126 or higher | 7.0 or higher |
Note: These values are general guidelines and may vary slightly based on laboratory and individual factors. Always consult with your healthcare provider for accurate interpretation of your results.
Understanding these ranges allows you to:
- Recognize if your blood sugar levels are within a healthy range.
- Identify potential risks for prediabetes or diabetes.
- Collaborate more effectively with your healthcare provider to manage your health.
Online Conversion Tools
While the formula is simple, using an online conversion tool can provide quick and accurate results. Many free converters are available, simply search for "blood sugar converter mg/dL to mmol/L." These tools are especially handy if you need to perform multiple conversions or want to avoid manual calculations.

Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Diet: The type and amount of food you consume significantly affect blood sugar. High-carbohydrate foods, especially refined sugars, can cause a rapid increase in blood sugar.
- Physical Activity: Exercise helps lower blood sugar levels by increasing insulin sensitivity and allowing cells to use glucose for energy.
- Stress: Stress hormones can elevate blood sugar levels.
- Medications: Certain medications can impact blood sugar, either raising or lowering it. It's crucial to discuss any medications you're taking with your doctor.
- Illness: Illness, particularly infections, can also raise blood sugar levels.
- Sleep: Lack of sleep can affect hormones that regulate blood sugar, leading to higher levels.
Understanding how these factors affect your blood sugar is crucial for effective management, especially if you have diabetes.
Importance of Regular Monitoring
Regular monitoring of blood sugar is essential for individuals with diabetes or those at risk. Monitoring helps you:
- Track how your body responds to different foods and activities.
- Adjust medications or lifestyle choices as needed to maintain target levels.
- Prevent dangerous complications associated with high or low blood sugar.
Consult your healthcare provider to determine the appropriate monitoring frequency and target blood sugar ranges for your individual needs.
