Blood Sugar mg/dL to mmol/L: Understanding and Converting Your Numbers
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. Blood sugar, or glucose, is measured using different units worldwide: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article breaks down how to understand and convert blood sugar readings between these two units.
Why Different Units for Blood Sugar Measurement?
The use of mg/dL and mmol/L depends largely on geographical location. In the United States, mg/dL is the standard unit, while mmol/L is commonly used in Canada, Europe, and other parts of the world. Both units measure the concentration of glucose in your blood, just expressed in different terms. Understanding both can be useful, especially when traveling or encountering medical information from different sources.
Understanding mg/dL and mmol/L Values
- mg/dL (milligrams per deciliter): This measurement indicates the mass of glucose (in milligrams) in a deciliter (100 milliliters) of blood.
- mmol/L (millimoles per liter): This indicates the number of moles of glucose (in millimoles) in a liter of blood. A mole is a standard unit of measurement for the amount of a substance.
Knowing the normal ranges for both units is crucial. The following are general guidelines; always consult your healthcare provider for personalized advice:
- Normal fasting blood sugar (mg/dL): 70-100 mg/dL
- Normal fasting blood sugar (mmol/L): 3.9-5.6 mmol/L
- Normal blood sugar 2 hours after eating (mg/dL): Less than 140 mg/dL
- Normal blood sugar 2 hours after eating (mmol/L): Less than 7.8 mmol/L
Converting mg/dL to mmol/L
The conversion between mg/dL and mmol/L is straightforward. Here's the conversion factor and formula:

- Conversion Factor: 1 mmol/L = 18 mg/dL
- Converting mg/dL to mmol/L: Divide the mg/dL value by 18.
- Formula: mmol/L = mg/dL ÷ 18
Example: If your blood glucose reading is 126 mg/dL, the equivalent in mmol/L is:

126 mg/dL ÷ 18 = 7 mmol/L
Therefore, 126 mg/dL is equal to 7 mmol/L.
Converting mmol/L to mg/dL
To convert mmol/L to mg/dL, you multiply the mmol/L value by 18.
- Formula: mg/dL = mmol/L x 18
Example: If your blood glucose reading is 6.1 mmol/L, the equivalent in mg/dL is:
- 1 mmol/L x 18 = 109.8 mg/dL
Therefore, 6.1 mmol/L is equal to 109.8 mg/dL.
Practical Conversion Table
Here’s a handy conversion table for common blood sugar readings:
| mg/dL | mmol/L |
|---|---|
| 70 | 3.9 |
| 90 | 5.0 |
| 100 | 5.6 |
| 126 | 7.0 |
| 140 | 7.8 |
| 180 | 10.0 |
| 200 | 11.1 |
| 250 | 13.9 |
| 300 | 16.7 |

Consistent blood sugar monitoring is essential for individuals with diabetes, as it allows them to:
- Track Glucose Levels: Understand how your body responds to food, exercise, and medication.
- Adjust Treatment Plans: Work with your healthcare provider to make informed decisions about your insulin dosages, diet, and physical activity.
- Prevent Complications: Maintaining stable blood sugar levels reduces the risk of long-term complications such as nerve damage, kidney disease, and heart disease.
Factors Affecting Blood Sugar Levels
Numerous factors can influence blood sugar, including:
- Diet: The type and amount of carbohydrates consumed significantly impact glucose levels.
- Physical Activity: Exercise can lower blood sugar, but intense activity may temporarily raise it in some individuals.
- Medications: Insulin and other diabetes medications are designed to regulate blood sugar.
- Stress: Stress hormones can elevate blood glucose.
- Illness: Infections and illnesses often cause blood sugar to rise.
- Time of Day: Blood sugar levels tend to fluctuate throughout the day, influenced by hormonal changes and metabolic processes.
Consulting with Healthcare Professionals
It's important to discuss your blood sugar readings and targets with your healthcare provider. They can provide personalized advice based on your individual health status, treatment plan, and lifestyle. Don't rely solely on general information or conversion tools without professional guidance.
Conclusion
Understanding the difference between mg/dL and mmol/L is a helpful skill for anyone managing their blood sugar. Being able to convert between the two units can assist in interpreting medical information accurately, especially when traveling or using resources from different countries. Use this guide along with the resources available and work closely with your healthcare provider to maintain healthy blood sugar levels and overall well-being.
