` :By all means make corrections, but please don't keep reverting everthing I do. I re-inserted the ``official documents``, as you could have yourself, without the need to revert the image caption and other changes I made to improve and add depth to the content. That the EU choose to use the word ``symbol`` to describe for their favoured abbreviation of ``kilometres per hour`` does not mean that we have to. And it does not mean you need to revert all my other changes if you insist on denying the use of ``abbreviation`` as a valid description in English for the shortening or contraction of the phrase ``kilometres per hour`` to ``km/h``. As for the extent of use of ``kph``, how do you suggest we qualify it? A google count? Examples of a cross-section of government documents, press documents, websites, &co; in which it appears? What should we do if we find its use is more frequent in all areas than ``km/h``?   `
