Parts Per Trillion Formula

The following formula is used to calculate the parts per trillion (PPT) for a given amount of substance and total amount. 

PPT = (A / T) * 10^{12}

Variables:

  • PPT is the parts per trillion
  • A is the amount of substance
  • T is the total amount

To calculate the parts per trillion, divide the amount of substance by the total amount. Multiply the result by 1012 to convert to parts per trillion.

What is Parts Per Trillion?

Parts per trillion (PPT) is a unit of measurement used to describe the concentration of one substance in a larger mixture. It is commonly used in environmental science, chemistry, and biology to measure extremely low concentrations of pollutants, contaminants, or other substances. One part per trillion means that there is one part of the substance for every trillion parts of the total mixture. This unit is useful for detecting and quantifying trace amounts of substances that can have significant effects even at very low concentrations.

How to Calculate Parts Per Trillion?

The following steps outline how to calculate the parts per trillion (PPT).

  1. First, determine the amount of substance (A).
  2. Next, determine the total amount (T).
  3. Next, calculate the parts per trillion using the formula PPT = (A / T) * 1012.
  4. Finally, calculate the parts per trillion.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Amount of substance (A) = 0.0005 grams

Total amount (T) = 1000 grams
