Worked example

1.15 ng/mL (middle of the reference range) = 4.02 nmol/L

Conversion formulas

nmol/L	nmol/L = ng/mL × 3.491	ng/mL = nmol/L × 0.2864
ng/dL	ng/dL = ng/mL × 100	ng/mL = ng/dL × 0.01
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10
ng/L	ng/L = ng/mL × 1000	ng/mL = ng/L × 0.001
pmol/L	pmol/L = ng/mL × 3491	ng/mL = pmol/L × 0.0002864
