ng/mL nmol/L µg/dL ng/dL ng/L

Worked example

10 ng/mL (middle of the reference range) = 10.9 nmol/L

Conversion formulas

nmol/L	nmol/L = ng/mL × 1.094	ng/mL = nmol/L × 0.9142
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10
ng/dL	ng/dL = ng/mL × 100	ng/mL = ng/dL × 0.01
ng/L	ng/L = ng/mL × 1000	ng/mL = ng/L × 0.001

Reference range

Unit	Adults
ng/mL	5 – 15
nmol/L	5.469 – 16.41
µg/dL	0.5 – 1.5
ng/dL	500 – 1500
ng/L	5000 – 15 000
