Frequently Asked Questions

For glucose, mmol/L = mg/dL ÷ 18.0182. To convert back, mg/dL = mmol/L × 18.0182. This calculator applies those conversions locally in your browser.

Glucose normally rises after eating, so a 2-hour post-meal reading is interpreted with higher thresholds than a fasting reading. Use the context that matches how the sample was taken.

No. It converts units and shows common reference bands only. Diagnosis requires proper testing, repeat confirmation when appropriate, symptoms, medications and clinical review.
