Convert mole percent to mole-based ppm or reverse ppm to mole percent. Choose the value to find, then enter the known value.

Use mole percent of one component in the mixture.

Mole basis only: ppm = µmol/mol. This is not a mass-fraction or mg/L conversion.

Mole Percent To PPM Formula

The following formula is used to convert Mole Percent to PPM and vice versa.

ppm = MP × 10000

Variables:

  • ppm is parts per million on a mole basis, numerically µmol/mol; mole percent must be from 0 to 100 and ppm from 0 to 1,000,000
  • MP is the mole percent

To convert Mole Percent to PPM, multiply the mole percent by 10000. To convert PPM to Mole Percent, divide the PPM by 10000.

What is Mole Percent?

Mole percent is a way of expressing the concentration of a component in a mixture. It is defined as the number of moles of a component divided by the total number of moles of all components in the mixture, multiplied by 100. This unit is commonly used in chemistry to describe the composition of chemical mixtures and solutions.

How to Calculate Mole Percent To PPM?

The following steps outline how to calculate Mole Percent to PPM.

  1. First, determine the mole percent (MP).
  2. Next, multiply the mole percent by 10000 to get PPM.
  3. If you have PPM and need to find Mole Percent, divide the PPM by 10000.
  4. Finally, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Mole Percent (MP) = 0.5%

PPM = 5000 ppm
