Enter the concentration in micromolar and the molecular weight of the substance to convert to parts per million (ppm).
Micromolar to PPM Formula
The following formula is used to convert micromolar (µM) concentration to parts per million (ppm):
ppm = (µM * MW) / 1000
Variables:
- µM is the concentration in micromolar
- MW is the molecular weight of the substance in grams per mole (g/mol)
- ppm is the concentration in parts per million
To convert micromolar to ppm, multiply the concentration in micromolar by the molecular weight and then divide by 1000.
What is Micromolar?
Micromolar (µM) is a unit of concentration used in chemistry to denote the number of moles of a substance in one liter of solution. It represents one-millionth of a molar concentration. This unit is commonly used in biological and chemical sciences to express low concentrations of substances.
What is PPM?
Parts per million (ppm) is a unit of measurement used to describe the concentration of a substance in a solution or mixture. It denotes the number of parts of a substance in a million parts of the total solution or mixture. PPM is commonly used in environmental science, chemistry, and engineering to express very dilute concentrations.
How to Convert Micromolar to PPM?
The following steps outline how to convert micromolar to ppm:
- First, determine the concentration in micromolar (µM).
- Next, determine the molecular weight of the substance (MW) in grams per mole.
- Use the formula ppm = (µM * MW) / 1000.
- Finally, calculate the concentration in parts per million (ppm).
- 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.
Concentration in micromolar (µM) = 150 µM
Molecular weight of the substance (MW) = 58.44 g/mol
