Worked example

3.605 mmol/L (middle of the reference range) = 64.9 mg/dL

Conversion formulas

mg/dL	mg/dL = mmol/L × 18.01	mmol/L = mg/dL × 0.05551
g/L	g/L = mmol/L × 0.1802	mmol/L = g/L × 5.551
mg/L	mg/L = mmol/L × 180.2	mmol/L = mg/L × 0.005551
µmol/L	µmol/L = mmol/L × 1000	mmol/L = µmol/L × 0.001

Reference range
