How do I convert 5-Methyltetrahydrofolate (CSF) from ng/mL to nmol/L?

nmol/L = ng/mL × 2.176. In the other direction: ng/mL = nmol/L × 0.4595.

Which units are used for 5-Methyltetrahydrofolate (CSF)?

Common units are ng/mL, nmol/L.

Urine & CSF

5-Methyltetrahydrofolate in cerebrospinal fluid (cerebral folate deficiency)

Also known as: 5-Methyltetrahydrofolat (Liquor)

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

ng/mL nmol/L

10 nmol/L = 4.6 ng/mL

nmol/L	nmol/L = ng/mL × 2.176	ng/mL = nmol/L × 0.4595

5-Methyltetrahydrofolate (CSF) is reported in ng/mL or nmol/L. The page converts between the units only.

nmol/L × 0.4595 = ng/mL (exact factor 0.4595).
CSF values are only meaningful together with a blood sample taken at the same time; no established reference range is listed here.
