mg/dL vs. mmol/L: How to Read Your Blood Sugar Test Results
Understanding your blood sugar test results is vital for managing diabetes or pre-diabetes. However, test results can be confusing because they're often reported in different units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article clarifies the difference between these units, explains how to convert between them, and helps you interpret your blood sugar levels effectively.
What are mg/dL and mmol/L?
- mg/dL (milligrams per deciliter): This is the unit most commonly used in the United States to measure blood glucose concentration. It indicates how many milligrams of glucose are in one deciliter (100 milliliters) of blood.
- mmol/L (millimoles per liter): This unit is predominantly used in many other parts of the world, including Canada and Europe. It represents the number of millimoles of glucose in one liter of blood.
Essentially, both units are measuring the same thing – the concentration of glucose in your blood – but expressing it differently. This can lead to confusion when comparing results from different labs or countries. Understanding both is crucial, especially when traveling or discussing results with international medical professionals. Accurate reading of your blood sugar test results hinges on knowing which units are being used.

The use of different units boils down to historical and regional preferences. The metric system is more widely adopted globally, making mmol/L the standard in many regions. The United States, however, primarily uses the imperial system, leading to the continued use of mg/dL. From a scientific perspective, both are valid methods of measuring glucose concentration, but standardization on a global scale remains a challenge. Familiarizing yourself with both mg/dL and mmol/L ensures you can accurately interpret blood sugar readings regardless of where the test was performed.
How to Convert Between mg/dL and mmol/L
Converting between mg/dL and mmol/L is straightforward:
- mg/dL to mmol/L: Divide the mg/dL value by 18.
- mmol/L to mg/dL: Multiply the mmol/L value by 18.
For example:
- If your blood sugar is 100 mg/dL, converting to mmol/L gives you 100 / 18 = 5.56 mmol/L.
- If your blood sugar is 7 mmol/L, converting to mg/dL gives you 7 * 18 = 126 mg/dL.
Knowing this simple conversion allows you to easily switch between the two measurements, improving your understanding of blood glucose levels. It’s also beneficial to use online converters, available for a quick and reliable conversion.

Understanding Normal Blood Sugar Ranges
Understanding what constitutes a normal blood sugar range is critical in both mg/dL and mmol/L. Here’s a comparison:

| Category | mg/dL | mmol/L |
|---|---|---|
| Fasting Blood Sugar (Normal) | Less than 100 | Less than 5.6 |
| Fasting Blood Sugar (Prediabetes) | 100-125 | 5.6-6.9 |
| Fasting Blood Sugar (Diabetes) | 126 or higher | 7.0 or higher |
| After Meal (2 hours) (Normal) | Less than 140 | Less than 7.8 |
| After Meal (2 hours) (Diabetes) | 180 or higher | 10.0 or higher |
Understanding these ranges empowers you to monitor your health and make informed decisions. Keep in mind that these are general guidelines, and your healthcare provider might suggest different targets based on your individual health profile. Knowing your target blood glucose range is an essential component of diabetes management.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, causing them to fluctuate throughout the day. These include:
- Diet: The type and amount of food you eat have a direct impact. High-carbohydrate foods can cause a rapid increase in blood sugar.
- Physical Activity: Exercise can help lower blood sugar as your muscles use glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, including steroids and some diuretics, can affect blood sugar.
- Illness: Being sick can also impact blood sugar levels due to hormonal changes and inflammatory responses.
- Time of Day: Blood sugar levels can naturally fluctuate throughout the day due to hormonal cycles.
By recognizing these factors, you can better manage your blood sugar levels through lifestyle adjustments and close monitoring.
Monitoring Your Blood Sugar
Regular blood sugar monitoring is essential for managing diabetes. Here's how to do it effectively:
- Frequency: Work with your healthcare provider to determine how often you should check your blood sugar. This may vary depending on the type of diabetes you have, your medication regimen, and lifestyle factors.
- Testing Devices: Use a reliable blood glucose meter and follow the manufacturer's instructions carefully. Ensure your meter is calibrated correctly.
- Record Keeping: Keep a log of your blood sugar readings, including the date, time, and any relevant information such as meals, activities, and medications. This log can help you and your healthcare provider identify patterns and make informed decisions about your treatment plan.
- Continuous Glucose Monitoring (CGM): Consider using a CGM system, which provides continuous tracking of blood glucose levels throughout the day and night. This can help you identify trends and make proactive adjustments to your treatment plan.
Effective blood sugar management requires consistent monitoring and collaboration with your healthcare team.
What to Do if Your Blood Sugar is Too High or Too Low
Knowing what to do when your blood glucose levels are outside the target range is critical for avoiding serious complications.
- High Blood Sugar (Hyperglycemia): If your blood sugar is consistently high, contact your healthcare provider. You may need to adjust your medication, diet, or exercise plan. Short-term steps include drinking water to help dilute glucose in the blood and engaging in light physical activity if you are able.
- Low Blood Sugar (Hypoglycemia): If your blood sugar is too low (typically below 70 mg/dL or 3.9 mmol/L), take immediate action. Consume 15-20 grams of fast-acting carbohydrates, such as glucose tablets, juice, or regular soda. Wait 15 minutes and recheck your blood sugar. If it is still low, repeat the process. Once your blood sugar is back in the target range, have a meal or snack to prevent it from dropping again.
It's crucial to educate yourself and your loved ones about the signs and symptoms of both hyperglycemia and hypoglycemia. Carry a source of fast-acting carbohydrates with you at all times. And always seek medical advice for managing blood sugar imbalances.
Working with Your Healthcare Provider
Your healthcare provider plays a pivotal role in managing your blood sugar and overall diabetes care. Be sure to:
- Share Your Blood Sugar Logs: Provide your healthcare provider with accurate and detailed blood sugar logs, including any patterns or trends you've noticed.
- Discuss Your Concerns: Don't hesitate to discuss any concerns, questions, or challenges you're facing in managing your diabetes.
- Follow Their Recommendations: Adhere to their prescribed treatment plan, including medication, diet, and exercise recommendations.
- Regular Check-ups: Attend regular check-ups to monitor your blood sugar levels, assess your overall health, and make any necessary adjustments to your treatment plan.
- Ask Questions: Be proactive in asking questions about your condition, treatment options, and ways to improve your blood sugar control.
By partnering with your healthcare provider and actively participating in your diabetes management, you can improve your health outcomes and quality of life.
Conclusion
Understanding the difference between mg/dL and mmol/L is a crucial step in effectively managing your blood sugar levels. By learning how to convert between these units, recognizing normal blood sugar ranges, and actively monitoring your blood sugar, you can take control of your health and prevent diabetes-related complications. Regular communication with your healthcare provider is also essential for developing a personalized management plan tailored to your individual needs. Stay informed, stay proactive, and prioritize your health.
