Blood Glucose Unit Converter

Convert between mg/dL and mmol/L and compare against common fasting and post-meal reference bands. Not medical advice.

What factor converts mg/dL to mmol/L?

Glucose conversions commonly use dividing mg/dL by 18.018 (≈18) to get mmol/L, or multiplying mmol/L by 18 to get mg/dL. This tool applies the standard clinical conversion factor.

Why do countries use different units?

The United States typically reports mg/dL, while many other regions use mmol/L. Both describe the same concentration — only the unit scale changes.

Can this diagnose diabetes?

No. Reference bands are educational summaries of common guidelines. Diagnosis and treatment require professional medical evaluation.
