How do I convert Beta-endorphin (CSF) from pg/mL to pmol/L?

pmol/L = pg/mL × 0.2886. In the other direction: pg/mL = pmol/L × 3.465.

Which units are used for Beta-endorphin (CSF)?

Common units are pmol/L, pg/mL.

Neurology & psychiatry

Beta-endorphin in cerebrospinal fluid (pain modulation)

Also known as: Beta-Endorphin (Liquor)

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

pmol/L pg/mL

1 pmol/L = 3.46 pg/mL

pmol/L	pmol/L = pg/mL × 0.2886	pg/mL = pmol/L × 3.465

Beta-endorphin (CSF) is reported in pg/mL or pmol/L. The page converts between the units only.

pmol/L × 3.465 = pg/mL (exact factor 3.465).
CSF values are only meaningful together with a blood sample taken at the same time; no established reference range is listed here.
