How the conversion works
One millimole of glucose per litre equals 18.0182 milligrams per decilitre, from the molar mass of glucose. So 28.5 mmol/L times 18.0182 is 514 mg/dL, rounded to the whole number that meters display. The exact factor matters: rounding it to 18 drifts readings by a couple of mg/dL at the top of the scale.

General information, not medical advice. Reference ranges follow the ADA diagnostic criteria; a single meter reading is not a diagnosis, which requires laboratory testing, usually confirmed on two occasions. See how we calculate.
Stop looking numbers up one at a time
A page can tell you what a reading means in general. Your own log tells you what it means for you: log a reading in seconds and SteadyRange shows your time in range, estimated A1C, and the patterns behind them, on a private log you control.
