Conversion Formula
mmol/L → mg/dL: Multiply by 18.0182
mg/dL → mmol/L: Divide by 18.0182
The factor 18.0182 is based on the molecular weight of glucose (180.182 g/mol).
mg/dL → mmol/L: Divide by 18.0182
The factor 18.0182 is based on the molecular weight of glucose (180.182 g/mol).
How to Use This Converter
Type a value in either the mmol/L or mg/dL field. The converter will instantly calculate and display the equivalent value in the other unit, along with a glucose level interpretation based on standard fasting glucose reference ranges.
