GlucoConvert

Stop doing glucose unit maths in your head. Whether you manage diabetes, care for someone who does, or work in healthcare — GlucoConvert is the fast, beautiful reference tool that converts either way between mmol/L and mg/dL instantly. THE CHART Scroll through every reading from 1.0 to 33.3 mmol/L in 0.1 increments, with the mg/dL equivalent (18-600 mg/dL) right beside it. Colour-coded by zone — Low (red), Target (green), High (yellow), Very High (amber) — so you always know at a glance where any reading sits. Type any number in the search bar and jump straight to it, in either unit. THE CALCULATOR Type any reading and convert it instantly, in both directions. mmol/L to mg/dL or mg/dL to mmol/L. The result shows the zone colour so you always have context. PERSONALISE IT Set your own target range thresholds — because everyone's numbers are different. Adjust text size (all the way up to Maximum for vision-impaired users), switch between light and dark mode, and customise zone colours.
