Part per million (ppm) is a widely used unit and often misunderstood. When one is confronted with the unit ppm, one of the first things one might want to consider is whether the units are indeed part per million by volume (ppmv) or part per million by mass (ppmw). When people report ppm, they mean ppmv or ppmw.

For the calculator on this page, it doesn't matter whether you're using ppm, ppmv, or ppmw.

If percentages, percents, and milligrams are still confusing, try this PPM calculator. It will make them a lot easier for you to understand.

A conversion factor from percentage units to parts per million or parts per billion is a simple tool that is often useful for converting percentages into units such as percent or parts per billion. In this article, we'll provide you with a brief introduction to each of the proportion metrics and explain how to calculate the numbers.

It’s an online parts per million (PPM) to percentage converter. It can convert units between ppm and percent or vice versa with a metric conversion table.

### PPM:

PPM stands for "parts per million" and it is utilized to calculate the concentration of the solution in air or water. It can even be expressed in milligrams per liter(mg/L).

### PPB:

PPB stands for "parts per billion" and it is utilized to calculate the concentration of the solution(mass fraction or mole fraction ). 1 ppb is equal to 1 µg/l.

### PPT:

PPT stands for "parts per trillion" and it is utilized to calculate the concentration of the solution in air or water. 1 PPT is equivalent to 1 nanogram per kilogram.
