How are camera sensor sizes measured?

I just stumbled upon the confusing fact that the dimension of a 1 inch sensor is 15.86mm x 13.2mm x 8.80mm. This isn't an inch in either length, height, or width, and the hypotenuse is not an inch either in 2D or 3D. What gives? Can anyone explain the "inch" nomenclature in sizing sensors?
