Understanding PPM to Percent Conversion

What is PPM?

PPM stands for "Parts Per Million". It's a way of expressing very dilute concentrations of substances. Just as percent means out of a hundred, so PPM means out of a million. For example, 100 ppm equals 0.01%.

Formula for Converting PPM to Percent

The formula to convert PPM to Percent is:

\[Percentage = \frac{PPM}{10,000}\]

Where:

• PPM is the parts per million value
• 10,000 is the conversion factor (since 1% = 10,000 PPM)

Calculation Steps

To convert PPM to Percent:

1. Take the PPM value
2. Divide it by 10,000
3. The result is the equivalent percentage

Example Calculation

Let's convert 5000 PPM to a percentage:

\[Percentage = \frac{5000}{10,000} = 0.5\%\]
