µmol/L mg/L = µg/mL mg/dL µg/dL

Worked example

15 mg/L (middle of the reference range) = 10.3 µmol/L

Conversion formulas

µmol/L	µmol/L = mg/L × 0.69	mg/L = µmol/L × 1.449
mg/dL	mg/dL = mg/L × 0.1	mg/L = mg/dL × 10
µg/dL	µg/dL = mg/L × 100	mg/L = µg/dL × 0.01

Reference range

Unit	Adults
µmol/L	6.9 – 13.8
mg/L = µg/mL	10 – 20
mg/dL	1 – 2
µg/dL	1000 – 2000
