How to Convert Part-per Million to Part-per BillionPart-per Billion

1 ppm = 1000 ppb
1 ppb = 0.001 ppm

Example: convert 20 ppm to ppb:
20 ppm = 20 x 1000 = 20000 ppb

Part-per Million

Definition: Parts per million (ppm) is a way of expressing very dilute concentrations of substances. It represents the number of parts of a substance per million parts of the mixture.

History/origin: The concept of parts per million arose out of the need to express very small concentrations of substances in a convenient way. It is widely used in chemistry, environmental science, and engineering.

Current use: PPM is commonly used to measure the concentration of pollutants in air and water, the concentration of trace elements in materials, and the concentration of additives in food and beverages.

Part-per Billion

Definition: Parts per billion (ppb) is a way of expressing extremely dilute concentrations of substances. It represents the number of parts of a substance per billion parts of the mixture.

History/origin: Similar to ppm, ppb was developed to express even smaller concentrations than ppm. It's a natural extension of the parts-per notation system.

Current use: PPB is used when measuring extremely low levels of contaminants or trace elements, for example, in sensitive environmental monitoring or in advanced chemical analysis.
