O knihe
High Quality Content by WIKIPEDIA articles! Parts-per notation is used, especially in science and engineering, to denote relative proportions in measured quantities; particularly in low-value (high-ratio) proportions at the parts-per-million (ppm) 10^-6, parts-per-billion (ppb) 10^-9, and parts-per-trillion (ppt) 10^-12 level. Since parts-per notations are quantity-per-quantity measures, they are known as dimensionless quantities; that is, they are pure numbers with no associated units of measurement. In regular prose, parts-per notations generally take the literal "parts per" meaning of a comparative ratio. However, in mathematical expressions, parts-per notations function as coefficients with values less than 1.
