Confused by mg/dL vs. mmol/L? A Simple Guide to Blood Sugar Units
Understanding blood sugar levels is crucial for managing diabetes and maintaining overall health. However, the different units used to measure blood glucose—specifically mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter)—can be confusing. This guide will simplify the conversion between these units and help you understand your blood sugar readings, regardless of which unit your meter uses.
Why Are There Different Units for Blood Sugar?
The use of mg/dL and mmol/L stems from different regional measurement standards. The United States typically uses mg/dL, while many other countries, including Canada and the UK, use mmol/L. The difference arises from how the concentration of glucose in the blood is expressed:
- mg/dL: Represents the mass of glucose (in milligrams) present in a specific volume of blood (one deciliter).
- mmol/L: Represents the molar concentration of glucose (in millimoles) present in a specific volume of blood (one liter).
Both units measure the same thing – blood glucose concentration – just in different ways. Understanding the relationship between them is essential for interpreting lab results, communicating with healthcare providers across different regions, or simply understanding diabetes resources from various sources.
Converting Between mg/dL and mmol/L
The key to converting between these units is a simple conversion factor: 1 mmol/L is approximately equal to 18 mg/dL.
- mg/dL to mmol/L: Divide the mg/dL value by 18. For example, 100 mg/dL ÷ 18 = approximately 5.5 mmol/L.
- mmol/L to mg/dL: Multiply the mmol/L value by 18. For example, 6 mmol/L x 18 = 108 mg/dL.

Let's look at some common blood sugar levels and their equivalents:
| Blood Sugar Level Description | mg/dL (Milligrams per Deciliter) | mmol/L (Millimoles per Liter) |
|---|---|---|
| Normal Fasting Blood Sugar | 70-99 mg/dL | 3.9-5.5 mmol/L |
| Prediabetes (Fasting) | 100-125 mg/dL | 5.6-6.9 mmol/L |
| Diabetes (Fasting) | 126 mg/dL or higher | 7.0 mmol/L or higher |
| Normal Blood Sugar 2 Hours After Meal | Less than 140 mg/dL | Less than 7.8 mmol/L |
Keep in mind that these are general guidelines and individual targets may vary based on individual health conditions and doctor's recommendations. Always consult your healthcare provider for personalized advice on blood sugar management.

Regardless of the units used, it's important to know what constitutes a healthy blood sugar range. Generally, the target ranges for people with diabetes are:
- Before meals: 80-130 mg/dL (4.4-7.2 mmol/L)
- 2 hours after starting a meal: Less than 180 mg/dL (10.0 mmol/L)
These targets can be different for individuals, especially children, the elderly, and pregnant women. Your doctor will help you determine the most appropriate target range for you. Maintaining your blood sugar within the recommended range is essential to minimize the risk of long-term complications associated with diabetes.
Tips for Managing Your Blood Sugar
Beyond understanding the units of measurement, actively managing your blood sugar is key to good health. Here are some important tips:
- Regular Monitoring: Check your blood sugar levels regularly as recommended by your doctor. Use a blood glucose meter and keep a record of your readings.
- Healthy Diet: Follow a balanced diet that includes plenty of fruits, vegetables, and whole grains. Limit your intake of sugary drinks, processed foods, and unhealthy fats.
- Regular Exercise: Engage in regular physical activity. Exercise helps lower blood sugar levels and improves insulin sensitivity.
- Medication Adherence: Take your diabetes medication as prescribed by your doctor. Do not skip doses or change the dosage without consulting your healthcare provider.
- Stay Hydrated: Drink plenty of water throughout the day to help your kidneys flush out excess sugar.
- Stress Management: Practice stress-reducing techniques like meditation, yoga, or deep breathing exercises. Stress can raise blood sugar levels.
- Regular Check-ups: Schedule regular appointments with your doctor to monitor your overall health and adjust your diabetes management plan as needed.
