Canon 1100d Sensor size in pixels

[Craigyboy3542]

Hi guys 

 I am using the following website so i can work out the image scale in arcsecs per pixel to put into Pixinsight, however I have been looking on the web and can only seem to find it in mm (22.2 x 14.7m)  and a pixel size of 5.2µm.

 Might sound stupid but do I just need to calculate 22.2x5.2 and 14.7x5.2 or is there something more technical involved as there seems to be with cameras sometimes

1 micron = 1/1000 mm, therefore 5.2microns = 0.0052mm.  22.2/0.0052   and 14.7/0.0052  = sensor size in pixels.

Thank you so much Peter 

I thought it maybe something different like that appreciate the help.
