g/dL g/L µmol/L mg/dL mmol/L

Worked example

42.5 g/L (middle of the reference range) = 4 250 mg/dL

Conversion formulas

g/dL	g/dL = g/L × 0.1	g/L = g/dL × 10
µmol/L	µmol/L = g/L × 15.04	g/L = µmol/L × 0.0665
mg/dL	mg/dL = g/L × 100	g/L = mg/dL × 0.01
mmol/L	mmol/L = g/L × 0.01504	g/L = mmol/L × 66.5

Reference range

Unit	Adults
g/dL	3.5 – 5
g/L	35 – 50
µmol/L	526.3 – 751.9
mg/dL	3500 – 5000
mmol/L	0.5263 – 0.7519
