It would be simpler to manually enter the camera sensor width rather than to calculate and enter the pixel size, especially since Photoscan automatically determines the pixel dimension of the photo when it is loaded.

Welcome
Maybe this image will make it even clearer, given the sensor width for the Caplio GX100 is 7.4mm:
Would be a lot easier to just enter the sensor width in mm.
I found the formula for focal length (pix) in this thread:
