The odd naming convention goes back to the dimensions of a
hypothetical glass tube that could surround the 1-inch sensor. Live
broadcasting cameras in the 1950s used cathode-ray tubes (CRT)
to project an image line after line. The glass tube that surrounded a
signal plate had a 1-inch diameter, although the photosensitive area
of the tube was only about 0.63" in diameter or around 16mm. The
typical diagonal of a modern 1-inch type sensor is, you guessed it,
16mm (15.9mm, to be precise).

Wow I didn't know that , hadn't really thought about it.
Now lets define the inch. :-D
The inch (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. It is equal to 1/36 yard or 1/12 of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used
(my thumb is 21.9mm ) does that mean I'm not human :-)
Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.

I beg to differ. According to the world-renowned authority, The Register, the approved small unit of length is the Linguine (lg). Larger units include the Double-Decker Bus and the (presumably Richard) Osman.Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.Naa the proper standard for an inch is 3 Barleycorns.

One inch is equivalent to 0.1818 linguines.

Non UKers may not understand this highly important unit of time.
