Open calculatorThe blood glucose converter changes glucose concentration between mg/dL and mmol/L. It performs unit conversion only; it does not classify the result as normal, high or low and does not diagnose diabetes or any other condition.
Enter a non-negative glucose value and choose the conversion direction. For mg/dL to mmol/L the calculator divides by 18.016. For mmol/L to mg/dL it multiplies by 18.016.
The entered value is a glucose concentration. The factor 18.016 is the fixed conversion factor implemented by this calculator. Results are rounded for display, so converting a rounded value back may differ slightly from the original.
180 mg/dL converts to 180 ÷ 18.016 = 9.99 mmol/L after display rounding. Conversely, 10 mmol/L converts to 10 × 18.016 = 180.16 mg/dL.
For medical decisions, use the original laboratory or meter result and follow guidance from a qualified healthcare professional. Do not change medication or treatment based only on this unit conversion.
No. It only changes measurement units. Interpretation depends on the type and timing of the test and should use appropriate clinical guidance.
The calculator displays a rounded result. Reusing that rounded number can introduce a small rounding difference.
No. The conversion is mathematical only and should not be used by itself for diagnosis or treatment decisions.
