Nikon D7100 vs V2: Which One is Denser?

Comparing two of my cameras for pixel density. I want to know what is the focal length multiplier if I crop the sensor image 1:1 at Full HD (1920 x 1080). I use Full HD as the benchmark as I often crop to this size for making desktop pictures.

Focal length multiplier
36 / 23.5 = 1.53x
