Preferred Name	RatioQuantity
Synonyms
Definitions	The class of quantities that are the ratio of two quantities with the same physical dimensionality. Quantities defined as ratios `Q=A/B` having equal dimensions in numerator and denominator are dimensionless quantities but still have a physical dimension defined as dim(A)/dim(B).
