How to convert ng/mL to µM
- Enter the value in ng/mL above. The unit is already set.
- Type the chemical formula (NaCl, C6H12O6) or the molar mass in g/mol. For a protein, use its mass in daltons: 66,500 for BSA.
- The table shows the concentration in µM and in every other unit.
Frequently asked questions
What is the formula to convert ng/mL to µM?
Concentration in g/L = molarity × molar mass, so a mass concentration divided by the molar mass gives moles per litre. Convert the prefixes from there: 1 mg/mL is 1 g/L, 1 µg/mL is 1 mg/L.
What is 1 ng/mL of NaCl in µM?
NaCl has a molar mass of 58.44 g/mol, so 1 ng/mL is 0.01711 µM.
Why do I need the molar mass?
ng/mL and µM measure different things: one counts mass, the other counts molecules. The molar mass, in grams per mole, links them, so the same mass of a heavy molecule is fewer moles.
