µM To µg/mL Formula
The following formula converts molar concentration in micromoles per liter (µM) to mass concentration in micrograms per milliliter (µg/mL), using the solute’s molar mass in g/mol.
Variables:
- C is mass concentration in micrograms per milliliter (µg/mL)
- c is molar concentration in micromoles per liter (µM)
- MW is molar mass in grams per mole (g/mol)
Multiply molarity in µM by molar mass in g/mol, then divide by 1,000 to obtain µg/mL. Since 1 µM is 10⁻⁶ mol/L and 1 g/L is 1,000 µg/mL, the combined factor is 10⁻³. Volume is not an input to this concentration conversion.
What is µM To µg/mL?
µM to µg/mL is a conversion from micromolar (uM) to micrograms per milliliter (ug/ml). This conversion is often used in scientific research, particularly in chemistry and biology, to express the concentration of a substance in a solution. The conversion factor depends on the molecular weight of the substance in question.
How to Calculate µM To µg/mL?
The following steps convert µM to µg/mL using C = c × MW / 1,000.
- First, determine the molar concentration c in µM.
- Next, determine the molar mass MW in g/mol for the exact chemical form of the solute.
- Multiply c by MW and divide by 1,000 to obtain concentration C in µg/mL.
- Keep the same solute and chemical-form assumptions when using the reverse conversion.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Molar concentration (c) = 50 µM
Molar mass (MW) = 500 g/mol. Result: 50 × 500 ÷ 1,000 = 25 µg/mL.
