From mg/dL to mmol/L: How to Read Your Blood Sugar Test Results

Understanding your blood sugar levels is crucial for managing diabetes or simply keeping tabs on your overall health. Blood sugar levels are typically measured in either milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L), depending on the country and laboratory practices. If you're faced with results in a unit you're unfamiliar with, it can be confusing. This article explains how to understand and convert between these two units so you can accurately interpret your blood sugar test results.

Why Different Units of Measurement?

The use of mg/dL is common in the United States, while mmol/L is generally preferred in Canada, Europe, and other parts of the world. Both units serve the same purpose: to measure the concentration of glucose in your blood. The difference simply reflects differing standardized practices across regions. Because different countries use different measurements, it is necessary to be able to convert from one to the other.

Understanding mg/dL (Milligrams per Deciliter)

mg/dL represents the weight of glucose (in milligrams) present in one deciliter of blood. This is the most commonly used unit in the US for displaying blood glucose levels. When reading your results, familiarize yourself with the typical ranges in mg/dL.

Understanding mmol/L (Millimoles per Liter)

mmol/L represents the number of moles of glucose present in one liter of blood. A "mole" is a standard unit of measurement used in chemistry. While this unit might seem less intuitive, it’s widely used internationally. If you are outside of the United States, this is the measurement you will see on blood glucose monitoring equipment.

How to Convert Between mg/dL and mmol/L

Here's how to convert between mg/dL and mmol/L:

mg/dL to mmol/L: Divide the mg/dL value by 18.
mmol/L to mg/dL: Multiply the mmol/L value by 18.

Example 1: Your blood sugar is 126 mg/dL. To convert to mmol/L: 126 / 18 = 7 mmol/L. A1C Chart And Eag Calculator Convert Your A1C To An Average Blood Sugar

Example 2: Your blood sugar is 6 mmol/L. To convert to mg/dL: 6 * 18 = 108 mg/dL.

Normal Blood Sugar Ranges in Both Units

Knowing the target blood sugar ranges is important for managing your health. These ranges can vary slightly depending on individual health conditions, age, and your doctor's recommendations. The general ranges are usually reported as:

Category	mg/dL (Fasting)	mmol/L (Fasting)
Normal	Less than 100	Less than 5.6
Prediabetes	100 to 125	5.6 to 6.9
Diabetes	126 or higher	7.0 or higher

Note: These are general guidelines, and your healthcare provider may recommend different targets based on your individual health status.

Why Is Monitoring Blood Sugar Important?

Regularly monitoring your blood sugar levels is especially important for people with diabetes. It helps you:

Manage medication dosage: Accurately adjust insulin or oral medications.
Make dietary choices: Understand how different foods impact your blood sugar.
Prevent complications: Avoid long-term health problems associated with high or low blood glucose.
Adjust lifestyle: Gauge the effects of physical activity and stress on your blood sugar.

Tips for Accurate Blood Sugar Monitoring

Here are some tips for reliable blood glucose monitoring:

Use a reliable meter: Choose a blood glucose meter that meets accuracy standards.
Follow instructions: Carefully adhere to the meter’s operating instructions.
Proper technique: Use the correct finger-pricking technique to obtain an adequate blood sample.
Regular calibration: Regularly calibrate the meter with control solutions.
Record results: Keep a log of your blood sugar readings for tracking and sharing with your healthcare provider.
Storage: Store strips correctly and do not use expired strips as they will produce inaccurate results.

When to Seek Medical Advice

Consult with your healthcare provider if you experience consistently high or low blood sugar levels, even after making lifestyle adjustments or following your treatment plan. Symptoms to watch out for include:

Frequent urination
Excessive thirst
Unexplained weight loss
Blurred vision
Slow-healing wounds
Fatigue
