Examples of 'ppmv' in a sentence
Meaning of "ppmv"
ppmv (noun) - 'PPMV' stands for 'Parts Per Million by Volume' and is a unit of measurement commonly used in environmental science and monitoring air quality. It quantifies the concentration of a particular gas as a ratio to the total volume of the mixture. Example: The ppmv of carbon dioxide in the atmosphere has been steadily increasing
