PPM and PPT are units of measurement used to express concentration:

## PPM

**PPM: Stands for “parts per million.”** It denotes the ratio of the number of parts of a substance to one million parts of the whole mixture. It’s commonly used for trace elements in solutions or pollutants in the environment.

## PPT

**PPT: Stands for “parts per trillion.”** It represents an even smaller concentration, where one part of a substance is found in one trillion parts of the mixture. It’s used to express extremely minute quantities, especially in advanced scientific contexts.

### How to convert ppm to ppt

Converting PPM (parts per million) to PPT (parts per trillion) involves multiplying the PPM value by 1000000. This is because there are 1000000 parts per trillion in one part per million.

**Formula: PPT = PPM × 1000000**

For example, if you have a concentration of 500 PPM, the equivalent value in PPT would be:

PPT = 500 PPM × 1000000 = 500,000,000 PPT

To convert PPM to PPT, simply multiply the PPM value by 1000000.
