When the value of such a quantity is expressed, the unit symbol 1 is generally not
17、written out explicitly. EXAMPLE Refractive index n = 133 x 1 = 1,53 Prefixes shall not be used to form multiples or submultiples of this unit. Instead of prefixes, powers of 10 may be used. EXAMPLE Reynolds number Re = 1,32 x 1 O3 Considering that plane angle is generally expressed as the ratio of t
18、wo lengths and solid angle as the ratio of two areas, in 1995 the CGPM has specified that, in the International System of Units, the radian, rad, and the steradian, sr, are “dimensionless” derived units. This implies that the quantities plane angle and solid angle are considered as derived quantitie
19、s of dimension one. The units radian and steradian may be omitted, or they may be used in expressions for derived units to facilitate distinction between quantities of different nature but having the same dimension. 1 Copyright International Organization for Standardization Provided by IHS under lic
