Our online PPM to Percent Converter is used to convert ppm (parts-per-million) value into a %.

PPM Conversion

Parts per million calculations are used for measuring small concentrations in a solution, solid and gas or the number of defects in manufacturing. The basic formula for PPM starts with dividing the weight or number of defects by the volume and then multiplying the result by 1,000,000. This formula is used by people in the agricultural industry for fertilizer calculations, by water treatment professionals, in swimming pool chlorine calculations, and in laboratories by chemists and others.


In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, “%”, or the abbreviations “pct.”, “pct”; sometimes the abbreviation “pc” is also used. A percentage is a dimensionless number (pure number).

What is PPM (Part Per Million)

PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

Convert ppm to percent

1% = 1/100
1ppm = 1/1000000
1ppm = 0.0001%
So to convert from ppm to percent, divide the ppm by 10000:
x(%) = x(ppm) / 10000

Example: find how many percent are in 300ppm.
x(%) = 500ppm / 10000 = 0.05%
