www.researchgate.net/post/What_is_a_refractive_index_unit RIU (refractive index unit) is a convenient unit to quantify the sensitivity of a surface plasmon resonance instrument. I believe that this is different from the conventional refractive index.
https://answers.yahoo.com/question/index?qid=... Best Answer:: It doesn't have units. If it did, the following equation which is true would not make sense: v = c/n (in a material with index n, since both v and c have m/s as the unit)
https://ca.answers.yahoo.com/question/index?qid=... Best Answer:: refractive index is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium . As it is a ratio it is unitless . The units m/s or km/h cancel out each other.
