mg/dL mg/L µg/dL µg/L

Worked example

1.5 mg/L (middle of the reference range) = 0.15 mg/dL

Conversion formulas

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
µg/L	µg/L = mg/L × 1000	mg/L = µg/L × 0.001

Reference range

Unit	Adults
mg/dL	0 – 0.3
mg/L	0 – 3
µg/dL	0 – 300
µg/L	0 – 3000

Note from the source: Most healthy adults have levels below 0.3 mg/dL (3 mg/L). For cardiovascular risk the CDC/AHA categories are below 1 mg/L low, 1-3 mg/L average, above 3 mg/L high (Circulation 2003)

Frequently asked questions

How do I convert hs-CRP from mg/L to mg/dL?
