Synopsis: This information provides a printable reference chart and table for converting blood glucose readings between mg/dl and mmol/L, the two units most widely used to measure blood sugar concentration. In the United States, Germany, and several other countries, glucose is reported in mg/dl (milligrams per deciliter), while mmol/L (millimoles per liter) is the international standard, so this table offers a straightforward side-by-side reference for reading results across both systems. It applies the standard glucose conversion factor of 0.0555 and can be printed directly from the browser, making it a practical everyday tool for people managing diabetes, seniors monitoring their levels, caregivers, and anyone interpreting glucose values reported in an unfamiliar unit.
At a Glance
- 1 - The chart can be printed straight from a web browser using File then Print, or with the keyboard shortcut Command plus P on Mac and Ctrl plus P on Windows and Linux.
- 2 - The listed figures are approximate, as the mg/dl measurements have been shortened to two decimal places with no rounding applied.
- 3 - Readings above roughly 400 mg/dl, or 22.2 mmol/L, indicate severe hyperglycemia and would be treated as a medical emergency, though they are included for completeness rather than as typical values.
- Topic Definition: Blood Sugar Conversion
Blood sugar conversion is the process of translating a blood glucose reading from one unit of measurement to another, most commonly between milligrams per deciliter (mg/dl) and millimoles per liter (mmol/L). The mg/dl unit expresses the weight of glucose in a given volume of blood and is used in the United States, Germany, and a number of other countries, while mmol/L reflects molar concentration and serves as the international standard. The two are linked by a fixed conversion factor of 0.0555, so a value in mg/dl multiplied by 0.0555 gives the equivalent in mmol/L, allowing the same result to be understood accurately regardless of which unit a meter or laboratory reports.
Introduction
Our printable mg/dl to mmol/L table below forms part of our article on converting mg/dl to mmol/L blood sugar levels which also includes additional information on blood sugar concentration or blood glucose levels in the blood.
Main Content
Blood Sugar mg/dl to mmol/L Conversion Table
*mg/dL measurements shortened to 2 decimal places with no rounding.
The conversion factor used is 0.0555, which is the standard factor for converting mg/dL to mmol/L for glucose measurements.
Note: Extremely high values (above about 400 mg/dL or 22.2 mmol/L) are considered severe hyperglycemia and would be medical emergencies in real-life situations. The higher values are included for completeness of the conversion table, but they do not represent normal or even common blood glucose levels.
How to Print the Chart
To print the above chart click "File" and then "Print". Or, use a keyboard shortcut:
Mac: Command-key + p
Windows and Linux: Ctrl + p
In the window that appears, select the destination and change your preferred print settings.

Insights, Analysis, and Developments
Editorial Note: A clear conversion chart can save a good deal of guesswork for anyone who moves between healthcare systems, travels abroad, or compares meters and lab reports that use different units. Keeping a printed copy alongside a glucose monitor or in a diabetes care kit gives a fast, dependable point of reference without the need to recalculate by hand or rely on a connected device. As always, these figures are intended to help interpret readings rather than to replace the guidance of a doctor or diabetes care team, who can weigh any individual result against a person's wider health picture.
