How do I convert Ammonia (CSF) from µg/dL to µmol/L?

µmol/L = µg/dL × 0.5872. In the other direction: µg/dL = µmol/L × 1.703.

Which units are used for Ammonia (CSF)?

Common units are µmol/L, µg/dL.

Urine & CSF

Ammonia in cerebrospinal fluid (hepatic encephalopathy, urea cycle defects)

Also known as: Ammoniak (Liquor)

Enter a value in any unit and all other units fill in.

µmol/L µg/dL

1 µmol/L = 1.7 µg/dL

µmol/L	µmol/L = µg/dL × 0.5872	µg/dL = µmol/L × 1.703

Ammonia (CSF) is reported in µg/dL or µmol/L. The page converts between the units only.

µmol/L × 1.703 = µg/dL (exact factor 1.703).
CSF values are only meaningful together with a blood sample taken at the same time; no established reference range is listed here.
