ng/mL = µg/L nmol/L mg/L µmol/L µg/dL

Worked example

195 ng/mL (middle of the reference range) = 435 nmol/L

Conversion formulas

nmol/L	nmol/L = ng/mL × 2.23	ng/mL = nmol/L × 0.4484
mg/L	mg/L = ng/mL × 0.001	ng/mL = mg/L × 1000
µmol/L	µmol/L = ng/mL × 0.00223	ng/mL = µmol/L × 448.4
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10

Reference range

Unit	Adults
ng/mL = µg/L	120 – 270
nmol/L	267.6 – 602.2
mg/L	0.12 – 0.27
µmol/L	0.2676 – 0.6022
µg/dL	12 – 27
