Folate Unit Converter (ng/mL ↔ nmol/L)

Health Updated 14 Jun 2026

Convert folate lab values between ng/mL (nanograms per milliliter) and nmol/L (nanomoles per liter). Uses the standard conversion factor 2.266. Helpful for comparing international lab results and understanding folate/B12 deficiency screening.

Rates and fees change frequently. Always confirm the current figures with the official authority before relying on this result.
  • Conversion uses the folate molar mass factor of 2.266.

Formula

nmol/L = ng/mL × 2.266; ng/mL = nmol/L ÷ 2.266
  • Folate unit conversion: nmol/L = ng/mL × 2.266; ng/mL = nmol/L ÷ 2.266.
  • The conversion factor 2.266 is the molar mass ratio (molecular weight of folate).
  • Lab reference ranges vary. Check your lab's normal ranges for clinical interpretation.
  • This converter helps compare results from labs using different measurement units (US labs often use ng/mL; European and international labs use nmol/L).

Example Calculation

Inputs
  • Folate Value: 10

Suppose you enter: Folate Value = 10. The calculator applies the formula (nmol/L = ng/mL × 2.266; ng/mL = nmol/L ÷ 2.266) and shows all output values below. Change any input field to immediately see how the result changes.
