The sensors used by Nikon (and others) don't always have the same size, and more often than not are not exactly 1.5x crop.

Take the Nikons D40/50/60/70, for example, had a 23.7mm sensor width, so 1.519x crop factor. This is the biggest size by the way, so it should really be called 1.52x crop.

The D500 has a 23.5mm sensor width, so 1.532x crop factor. The Nikon D3200's sensor has 23.2mm width, 1.552x crop. The D3100, with 23.1mm sensor width, 1.558x crop.

 

My EOS M has a sensor width of 22.3mm, which makes it 1.614x crop. My EOS 6D has a 35.8mm sensor width, making it a 1.0056x crop.
