PPT to PPM Converter

Understanding PPT to PPM Conversion

What are PPT and PPM?

PPT (Parts Per Trillion) and PPM (Parts Per Million) are units used to measure extremely small concentrations of substances in mixtures. They are commonly used in chemistry, environmental science, and other scientific fields where precise measurements of trace amounts are necessary.

• PPT represents the number of parts of a substance per trillion parts of the mixture.
• PPM represents the number of parts of a substance per million parts of the mixture.

Conversion Formula

The formula to convert PPT to PPM is:

\[PPM = \frac{PPT}{1,000,000}\]

Where:

• PPM = Concentration in Parts Per Million
• PPT = Concentration in Parts Per Trillion

Calculation Steps

To convert PPT to PPM:

1. Start with the concentration in PPT
2. Divide the PPT value by 1,000,000
3. The result is the concentration in PPM

Example Calculation

Let's convert 5,000,000 PPT to PPM:

\[PPM = \frac{5,000,000}{1,000,000} = 5\]

Therefore, 5,000,000 PPT is equal to 5 PPM.

Visual Representation

This diagram illustrates the conversion of 5,000,000 PPT to 5 PPM. The colored portions represent the relative concentrations, showing that while the actual amount remains the same, the PPM value is numerically much smaller than the PPT value.
