Blood Sugar mg/dL to mmol/L: A Simple Conversion Guide & Chart
Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. Often, blood sugar results are reported in different units depending on the country or lab. Two common units are milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article provides a comprehensive guide and conversion chart to help you effortlessly convert between these units.
Why is it Important to Understand the Different Units?
Different regions and healthcare systems use different units for reporting blood glucose readings. For instance, the United States commonly uses mg/dL, while many other countries use mmol/L. Misunderstanding or being unable to convert between these units can lead to confusion and potentially incorrect management of your condition. By understanding the conversion, you can confidently interpret your blood sugar readings regardless of the unit used.
The Conversion Formula: mg/dL to mmol/L
The conversion from mg/dL to mmol/L is quite simple. You just need to divide the mg/dL value by 18.
Formula:
mmol/L = mg/dL / 18
For example, if your blood sugar reading is 126 mg/dL, you would convert it to mmol/L as follows:
mmol/L = 126 mg/dL / 18 = 7 mmol/L
Conversely, to convert mmol/L to mg/dL, you would multiply the mmol/L value by 18.
Formula:
mg/dL = mmol/L * 18

To make the conversion process even easier, refer to the following chart, which provides pre-calculated conversions for common blood sugar levels.
| mg/dL (Milligrams per Deciliter) | mmol/L (Millimoles per Liter) |
|---|---|
| 50 | 2.8 |
| 70 | 3.9 |
| 90 | 5.0 |
| 100 | 5.6 |
| 120 | 6.7 |
| 140 | 7.8 |
| 160 | 8.9 |
| 180 | 10.0 |
| 200 | 11.1 |
| 250 | 13.9 |
| 300 | 16.7 |
Understanding Normal Blood Sugar Ranges in Both Units
It's not enough just to convert the numbers; you need to understand what constitutes a normal range. Normal blood sugar ranges can vary slightly depending on factors like age, time of day, and whether you have diabetes. Here are general guidelines:
- Fasting Blood Sugar:
- mg/dL: 70-100 mg/dL
- mmol/L: 3.9-5.6 mmol/L
- 2 Hours After Eating:
- mg/dL: Less than 140 mg/dL
- mmol/L: Less than 7.8 mmol/L
For individuals with diabetes, target ranges may be different. It's crucial to discuss your specific target range with your healthcare provider. Maintaining optimal glucose control is essential for preventing complications.
Using Online Conversion Tools
While the formula is simple and the chart helpful, several online conversion tools are available to simplify the process further. These tools allow you to quickly convert between mg/dL and mmol/L by simply entering the value you want to convert. Just search for "blood sugar conversion calculator" on Google. Always double-check the results with the formula or chart, especially if relying on the conversion for medical decisions.
Why Consistency is Key for Blood Sugar Monitoring
Whether you are using mg/dL or mmol/L, the most important aspect is consistent blood sugar monitoring. Work with your healthcare team to determine which unit they prefer, and stick with it. This will help avoid confusion when tracking your readings and making treatment decisions. Also, make sure all your devices (glucose meters, continuous glucose monitors) are set to the same units. This consistency ensures accurate monitoring and effective management of your blood sugar levels.
Common Misconceptions about Blood Sugar Conversion
- Thinking the Units are Interchangeable: They are not! Failing to convert accurately can lead to wrong dosages of insulin or other medications.
- Ignoring Decimal Places: Accuracy is essential. Make sure you pay attention to decimal places in the conversion. For example, 6.67 mmol/L is significantly different from 6 mmol/L.
- Relying Solely on Memory: Use the chart or a calculator, especially when making critical decisions about your health.
