I would like to know how to pronounce a derived scientific unit.
From SI Unit and Prefix Names in Chinese, I have been able to surmise that A/B is pronounced A每B， such that g/m would be 克每米.
However, how is the product of units pronounced, such as A.B or g.m (gram-metres)?
And, how are ratios of products pronounced? For example， A.B / (C.D), such as kg.m / (J.s) (kilogram-metres per Joule-second in English)
