    Hi John, Here's a link to the molecular weight which I had mentioned is 316.5 https://pubchem.ncbi.nlm.nih.gov/compound/pregnenolone

      0.3 nmol/L x 316.5 g/mol = 95 ng/L
      As 1 dL = 0.1 L, it is 9.5 ng/dL

            More precisely, I need the conversion factor. Can you help me please?

              The key to converting between grams and moles is the molar mass or molecular weight; the rest is adjusting prefixes and the number.

              This sites http://www.cloud-clone.com/items/B212.html gives the MW as 49 kDa, implying a molar mass of 49 kg/mol

              plNote that ng/mL would be the same numeric value in g/L. To convert, multiply by 1 mol/49000 g

              as an example 50 g/L x 1 mol/49000 g = 1.02 nmol/L
