Part/Million Unit Conversions

What is the Part/Million unit?

The Part/Million (symbol: ppm, 10⁻⁶) is a pseudo unit that describes small values of miscellaneous quantities, for example, mole fraction or mass fraction. These fractions are dimensionless because they are quantity-per-quantity measures. Therefore, they are simply numbers. One part per million denotes one part per 1,000,000 parts and a value of 1 × 10⁻⁶. This can be compared to one drop of a liquid substance diluted into 50 liters of water. Other part-per units are commonly used: ppb (parts-per-billion, 10⁻⁹), ppt (parts-per-trillion, 10⁻¹²), and ppq (parts-per-quadrillion, 10⁻¹⁵).
