Worked example
3.26 µmol/L (middle of the reference range) = 175 µg/dL
Conversion formulas
| µg/dL | µg/dL = µmol/L × 53.69 | µmol/L = µg/dL × 0.01863 |
|---|---|---|
| mg/dL | mg/dL = µmol/L × 0.05369 | µmol/L = mg/dL × 18.63 |
| mg/L | mg/L = µmol/L × 0.5369 | µmol/L = mg/L × 1.863 |
| µg/L | µg/L = µmol/L × 536.9 | µmol/L = µg/L × 0.001863 |
| nmol/L | nmol/L = µmol/L × 1000 | µmol/L = nmol/L × 0.001 |
Good to know
Beta-carotene is reported in µg/dL or in µmol/L.
- µg/dL × 0.0186 = µmol/L (exact factor 0.018627).
- Blood levels reflect recent intake of carotene-rich foods and supplements.
