Blood Sugar mg/dL to mmol/L: The Easy Conversion Guide

Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. Blood sugar is typically measured in either milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). While mg/dL is commonly used in the United States, mmol/L is more prevalent in other parts of the world. This article will provide an easy guide on how to convert between these two units, why it's important, and offer resources for further learning.

Why is Converting Blood Sugar Units Important?

If you travel internationally, use medical devices manufactured in different countries, or simply read research from different sources, you may encounter both mg/dL and mmol/L.

Understand Your Blood Sugar Readings Regardless of Location: Stay informed no matter where you are or what device you're using.
Accurately Communicate with Healthcare Professionals: Provide consistent and correct information to your doctor, ensuring proper treatment.
Effectively Monitor Your Diabetes: Make informed decisions about your diet, exercise, and medication based on clear and accurate blood sugar readings.

The Conversion Formula: mg/dL to mmol/L and Vice Versa

The conversion between mg/dL and mmol/L is straightforward. Here are the formulas:

mg/dL to mmol/L: Divide the mg/dL value by 18 (mmol/L = mg/dL / 18)
mmol/L to mg/dL: Multiply the mmol/L value by 18 (mg/dL = mmol/L * 18)

Example:

Let's say your blood sugar reading is 100 mg/dL. To convert this to mmol/L, you would do the following:

100 mg/dL / 18 = 5.56 mmol/L

Therefore, 100 mg/dL is equal to approximately 5.56 mmol/L.

Conversely, if your blood sugar reading is 7 mmol/L, you convert to mg/dL like this:

7 mmol/L * 18 = 126 mg/dL

Thus, 7 mmol/L is equal to 126 mg/dL.

Quick Conversion Table

Here's a helpful table providing common blood sugar levels converted between mg/dL and mmol/L:

mg/dL (Milligrams per Deciliter)	mmol/L (Millimoles per Liter)
70	3.9
100	5.6
120	6.7
140	7.8
180	10.0
200	11.1
250	13.9
300	16.7

Normal Blood Sugar Ranges

Understanding normal blood sugar ranges is also important. These ranges can vary slightly based on factors like age, time of day, and whether you have diabetes. Generally, the following ranges are considered typical for adults without diabetes:

Fasting Blood Sugar: 70-99 mg/dL (3.9-5.5 mmol/L)
Two Hours After Eating: Less than 140 mg/dL (7.8 mmol/L)

People with diabetes typically have target ranges provided by their healthcare provider. These may differ from the ranges above.

Tools and Resources for Blood Sugar Conversion

Several online tools and mobile apps are available to help you quickly convert between mg/dL and mmol/L. Some popular options include:

Online Conversion Calculators: Search for "blood sugar conversion calculator" on Google or your preferred search engine. Many simple, free tools are readily available.
Diabetes Management Apps: Many diabetes apps, such as MySugr or Glucose Buddy, include built-in conversion tools and features for tracking blood sugar levels.
Healthcare Professional Consultations: Always discuss your blood sugar management plan and target ranges with your doctor or a certified diabetes educator (CDE). They can provide personalized guidance and support.

Potential Pitfalls to Avoid
