This converter converts parts per million (ppm) to weight percent (%) online.
The parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.
To calculate the mass percent or weight percent of a solution, you must divide the mass of the solute by the mass of the solution (both the solute and the solvent together) and then multiply by 100 to change it into percent.

Formula:
WP = PPM ÷ 10000
Where,WP = Weight Percent,
PPM = Parts Per Million
