Very low solute concentrations are often expressed using appropriately small units such as parts per million (ppm) or parts per billion (ppb). Like percentage (“part per hundred”) units, ppm and ppb may be defined in terms of masses, volumes, or mixed mass-volume units.

Use this concentration unit conversion tool to easily convert between parts per million (ppm), parts per billion (ppb), and parts per trillion (ppt). Essential for accurate and efficient concentration conversions in chemistry, environmental science, pharmaceuticals, and health safety.
PPB stands for parts per billion. One part per billion is one part of solute per one billion parts solvent . PPB is a commonly used unit of concentration for very small values.
One part per billion is equivalent to one microgram of a substance per liter of water or one microgram per cubic meter of air. ppb is commonly used in environmental science to measure pollutants, such as carbon monoxide and sulfur dioxide, to understand their impact on air quality.
