When dealing with chemical concentrations, air quality measurements, or any other scientific data, you might encounter units like parts per million (PPM) and percentages.

Understanding how to convert between these units is essential for interpreting data accurately.

What is PPM?

PPM stands for “parts per million,” a unit of measurement used to describe the concentration of one substance in a mixture. It is often used in environmental science, chemistry, and various engineering fields. One PPM means one part of a substance for every million parts of the whole mixture.

For example, 1 PPM of carbon dioxide (CO₂) in air means there is one molecule of CO₂ for every one million molecules of air.

Why Convert PPM to Percentage?

Converting PPM to percentage is useful when you need to express a concentration in a more commonly understood form. While PPM is suitable for very small concentrations, percentages are more intuitive and easier to communicate in everyday contexts.
