g/L mmol/L = mEq/L mg/dL g/dL mg/L

Worked example

101.5 mmol/L (middle of the reference range) = 360 mg/dL

Conversion formulas

g/L	g/L = mmol/L × 0.03545	mmol/L = g/L × 28.21
mg/dL	mg/dL = mmol/L × 3.545	mmol/L = mg/dL × 0.2821
g/dL	g/dL = mmol/L × 0.003545	mmol/L = g/dL × 282.1
mg/L	mg/L = mmol/L × 35.45	mmol/L = mg/L × 0.02821
