The Ultimate Blood Sugar Conversion Guide: From mg/dL to mmol/L
Understanding your blood sugar levels is crucial for managing diabetes or simply maintaining overall health. But deciphering those numbers can be confusing, especially when different countries and labs use different units of measurement. This comprehensive guide will help you master the blood sugar conversion from milligrams per deciliter (mg/dL) to millimoles per liter (mmol/L), providing you with the knowledge to interpret your results accurately.
Why Are There Different Units for Blood Sugar?
Different countries adopt different standard units for reporting blood glucose levels. In the United States, mg/dL is the common unit. However, many other countries, including Canada and most of Europe, use mmol/L. Knowing how to convert blood sugar levels between these two units is essential if you're traveling, communicating with international healthcare providers, or encountering lab results reported in a unit you're not familiar with. Using a blood sugar conversion chart or formula ensures you're always on the same page, allowing you to manage your health effectively.
The Conversion Formula: mg/dL to mmol/L
The magic number to remember for blood sugar conversion is 18.
To convert mg/dL to mmol/L, simply divide the mg/dL value by 18:

mmol/L = mg/dL ÷ 18
For example, if your blood sugar reading is 126 mg/dL, the equivalent mmol/L value is:
126 mg/dL ÷ 18 = 7 mmol/L
The Conversion Formula: mmol/L to mg/dL
Conversely, to convert mmol/L to mg/dL, multiply the mmol/L value by 18:
mg/dL = mmol/L × 18
For example, if your blood sugar reading is 5.5 mmol/L, the equivalent mg/dL value is:
5.5 mmol/L × 18 = 99 mg/dL
Quick Conversion Chart
For quick reference, here’s a handy blood sugar conversion chart:
| mg/dL | mmol/L |
|---|---|
| 70 | 3.9 |
| 90 | 5.0 |
| 100 | 5.6 |
| 110 | 6.1 |
| 126 | 7.0 |
| 140 | 7.8 |
| 160 | 8.9 |
| 180 | 10.0 |
| 200 | 11.1 |
This table offers a basic conversion. For greater accuracy, always use the conversion formula.
Understanding Blood Sugar Ranges
Knowing the target blood sugar ranges is just as important as converting the units. These ranges vary depending on whether you're testing before or after meals, and whether you have diabetes. Here's a general guideline, presented in both mg/dL and mmol/L:
| Condition | Target Range (mg/dL) | Target Range (mmol/L) |
|---|---|---|
| Fasting (No Diabetes) | 70-99 | 3.9-5.5 |
| Fasting (With Diabetes) | 80-130 | 4.4-7.2 |
| 2 Hours After Meal (No Diabetes) | Less than 140 | Less than 7.8 |
| 2 Hours After Meal (With Diabetes) | Less than 180 | Less than 10.0 |
These ranges are general guidelines. Always consult with your healthcare provider for personalized recommendations.
Online Blood Sugar Conversion Tools
Many convenient online blood sugar conversion calculators are available. These tools provide instant conversions, eliminating the need for manual calculations. Simply enter your value in either mg/dL or mmol/L, and the calculator will display the equivalent value in the other unit. Just search for "mg/dL to mmol/L converter" on any search engine.
