PPM PPB Converter

How to Convert Between PPM and PPB

Converting between parts per million (PPM) and parts per billion (PPB) is a common task in chemistry, environmental science, and water quality analysis. This calculator helps you easily switch between these two concentration units.

What are the Formulas?

The formulas for converting between PPM and PPB are:

\[ \text{PPB} = \text{PPM} \times 1,000 \]

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

Where:

• PPM is the concentration in parts per million
• PPB is the concentration in parts per billion

What are the calculation steps?

1. Identify whether you're starting with PPM or PPB
2. If converting from PPM to PPB, multiply the PPM value by 1,000
3. If converting from PPB to PPM, divide the PPB value by 1,000

Example Calculation

Let's convert 5 PPM to PPB:

Step 1: Identify the starting value

• PPM concentration = 5 PPM

Step 2: Apply the formula

PPB = 5 × 1,000 = 5,000 PPB

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

Diagram of PPM and PPB

The following diagram illustrates the relationship between PPM and PPB:

This diagram shows how PPM and PPB relate on a concentration scale. Note that 1 PPM equals 1,000 PPB, which is why we multiply or divide by 1,000 in our conversions.
