PPB to PPM Converter

Understanding PPB to PPM Conversion

What are PPB and PPM?

PPB (Parts Per Billion) and PPM (Parts Per Million) are units used to measure very small concentrations of substances in mixtures. They are commonly used in chemistry, environmental science, and other scientific fields.

• PPB represents the number of parts of a substance per billion 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 PPB to PPM is:

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

Where:

• PPM = Concentration in Parts Per Million
• PPB = Concentration in Parts Per Billion

Calculation Steps

To convert PPB to PPM:

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

Example Calculation

Let's convert 5000 PPB to PPM:

\[PPM = \frac{5000}{1,000} = 5\]

Therefore, 5000 PPB is equal to 5 PPM.

Visual Representation

This diagram illustrates the conversion of 5000 PPB to 5 PPM. The colored portions represent the relative concentrations, showing that while the actual amount remains the same, the PPM value is numerically smaller than the PPB value.
