Detailed guide to this category

Blood glucose results may be reported in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L), depending on the laboratory, country or device.

This converter changes the unit expression only. A laboratory result should be interpreted with the reference range, test context and guidance supplied by a qualified healthcare professional.

mg/dL and mmol/L

Both units describe the same glucose concentration. Milligrams per deciliter expresses mass per volume, while millimoles per liter expresses amount of substance per volume.

Use the unit printed on the report or device and convert only when a comparison requires the other reporting convention.

Using a converted result safely

A unit conversion does not diagnose a condition or establish a treatment target. Timing, test method, individual history and the laboratory reference range all affect how a result is interpreted.

For medical decisions or an unexpected result, follow the advice on the report and consult a qualified healthcare professional.

Comparing reports with different units

When comparing records, convert the value and retain the original unit, laboratory and test context. A change in unit display does not make results from different methods directly interchangeable.

Use the converter for unit expression only and rely on a qualified healthcare professional for interpretation or treatment decisions.
