Blood Sugar mg/dL to mmol/L: An Easy Conversion Guide
Understanding your blood sugar levels is crucial for managing conditions like diabetes and maintaining overall health. Blood sugar, or glucose, is usually measured in either milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L), depending on the region. This guide will provide a comprehensive breakdown of blood sugar conversion, helping you easily switch between mg/dL and mmol/L.
Why the Different Units?
Different countries use different units for measuring blood glucose. In the United States, mg/dL is commonly used, whereas many other countries, including Canada and European nations, use mmol/L. Knowing how to convert between the two is important, especially if you travel frequently or are comparing information from different sources. Furthermore, understanding both units allows for more versatile communication with healthcare professionals, regardless of their location.
The Simple Conversion Formulas
Converting between mg/dL and mmol/L is straightforward using these formulas:
- To convert mg/dL to mmol/L: Divide the mg/dL value by 18.
- Formula: mmol/L = mg/dL ÷ 18
- To convert mmol/L to mg/dL: Multiply the mmol/L value by 18.
- Formula: mg/dL = mmol/L × 18
These calculations are based on the molecular weight of glucose and the conversion factor between grams and milligrams, and liters and deciliters.
Practical Examples of Blood Sugar Conversion
Let’s look at some examples to make this clearer:
- Converting 100 mg/dL to mmol/L:
- mmol/L = 100 mg/dL ÷ 18
- mmol/L = 5.56
- Converting 7.2 mmol/L to mg/dL:
- mg/dL = 7.2 mmol/L × 18
- mg/dL = 129.6
Therefore, 100 mg/dL is equal to approximately 5.56 mmol/L, and 7.2 mmol/L is approximately 129.6 mg/dL.

Normal Blood Sugar Ranges
Knowing the normal blood sugar ranges in both units is critical. While target ranges can vary depending on individual circumstances and health conditions, here's a general guideline:
| Category | mg/dL | mmol/L |
|---|---|---|
| Fasting Blood Sugar (Normal) | Less than 100 | Less than 5.6 |
| Fasting Blood Sugar (Prediabetes) | 100 to 125 | 5.6 to 6.9 |
| Fasting Blood Sugar (Diabetes) | 126 or higher | 7.0 or higher |
| Postprandial (2 hours after eating, Normal) | Less than 140 | Less than 7.8 |
These ranges are generally accepted guidelines. Always consult with your healthcare provider for personalized advice based on your health status.
Online Conversion Tools
If you don’t want to do the math yourself, many free online converters are available. Simply enter the mg/dL or mmol/L value, and the tool will instantly perform the conversion. This is a convenient way to quickly verify your calculations or to convert numerous values at once. Just make sure to use reputable online sources for accurate results.

Accurate blood sugar measurement is critical for managing diabetes. It informs decisions about diet, exercise, and medication. Regularly monitoring your blood glucose and accurately interpreting the results, regardless of the units used, can prevent serious complications. This includes both immediate issues like hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar), as well as long-term complications affecting the eyes, kidneys, and nerves.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Diet: Carbohydrate intake, portion sizes, and the timing of meals.
- Physical Activity: Exercise can lower blood sugar levels.
- Medications: Some medications can raise or lower blood sugar.
- Stress: Stress hormones can affect blood glucose.
- Illness: Infections and other illnesses can cause fluctuations.
- Hydration: Dehydration can affect blood sugar concentration.

Tips for Managing Blood Sugar
Here are some practical tips for keeping your blood sugar levels in a healthy range:
- Follow a Balanced Diet: Focus on whole grains, lean proteins, and plenty of fruits and vegetables.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Blood Sugar: Check your blood sugar as directed by your healthcare provider.
- Stay Hydrated: Drink plenty of water throughout the day.
- Manage Stress: Practice stress-reducing techniques like meditation or yoga.
- Adhere to Medication: Take any prescribed medications as directed.
- Get Enough Sleep: Poor sleep can impact blood sugar control.
Common Mistakes to Avoid
- Inconsistent Testing: Irregular testing can lead to missed fluctuations.
- Incorrect Meter Usage: Always follow the manufacturer’s instructions for your glucose meter.
- Ignoring Symptoms: Pay attention to symptoms of high or low blood sugar.
- Improper Storage of Supplies: Store test strips properly to avoid inaccurate readings.
- Not Consulting Healthcare Provider: Don't make significant changes to your management plan without professional advice.
Conclusion
Understanding how to convert blood sugar values between mg/dL and mmol/L is a valuable skill for anyone managing diabetes or interested in their overall health. By using the simple conversion formulas and keeping the normal ranges in mind, you can confidently interpret your blood sugar readings and work effectively with your healthcare team. Remember to consistently monitor your blood sugar, maintain a healthy lifestyle, and consult with medical professionals for personalized guidance.
