Thanks.  I think it needs some adaptation here.  Our issue is the Associated 
Press Style Guide, which almost all media uses.  They regard kph as an 
acceptable abbreviation, and apparently don't understand that the SI assigns 
symbols as short forms, not abbreviations, and that those symbols have rules.  
However, the primary AP recommendation on metric is to omit it entirely, so 
there is a need to be somewhat subdued about criticism.  There is a genuine 
question of whether kph is better than no metric at all.

(However, pointing out that their competition, AFP, uses metric correctly may 
be 
the way to approach it.)

Dear John, 

Here is a letter that I used successfully in Australia some time ago. You may 
be 
able to adapt it to use in your local environment.

The Editor
The Age

Dear Editor,

I am appalled at the response of your 'Drive' editor to a letter written by
Bert Smith in Thursday's copy of 'The Age' (2003-04-24). I quote your
editor:

'The use of kmh is the style adopted by The Age and other Fairfax papers'.

>From which orphanage was this style adopted. It definitely did not come 
>from any 
reputable institution.

I have checked with the National Standards Commission in Australia, they use
the correct unit, km/h. I have referred to the 'International System of
Units (SI) 7th Edition 1998', and the website of the Bureau Internationale
de Poids et Mesures (BIPM), and they use km/h. To make sure, I also checked
with the National Institute of Standards and Technology in the USA; they use
km/h. All of these sources recommend km/h as the correct international
symbol for kilometres per hour.

The unit symbol, km/h, is correct because it demonstrates how the value was
obtained. If I drive 120 kilometres in 2 hours, I then calculate my speed as
120 divided by 2 to get 60 km/h. The fact that I divided one number by
another is included in the solidus (or slash) contained within the unit,
km/h. Your travesty of an abbreviation, kmh, is completely meaningless as it
implies multiplying 120 km by 2 h (to get 240 kmh?), rather than the correct
60 km/h obtained by division.

You are wrong in using kmh as an abbreviation for kilometres per hour. You
are wrong because you are ignoring all international agreements and
standards. You are also wrong because what you write, in the abbreviation
kmh, is simply wrong physics and wrong engineering.

Perhaps it was the nonchalance of your editor's explanation that raised my
ire. It seemed to me that the 'Drive' editor was saying to the Physics
teacher, Bert Smith, 'We are wrong when we use kmh, we know that we are
wrong, but we don't really care about you, your students, or, for that
matter, we don't really care about any other students in Australia, either'.

Yours faithfully,




Pat Naughtin

I am glad to see AP including (or leaving in) the metric in more stories that
