Pat, you said: "Our on-going problem with WHO charts in US is that in most 
places we still use pounds and inches :-( and I don't seeing it change 
anytime soon :-( " 

Here in the UK most parents use pounds and inches while medical 
professionals use kilos.  There are ways around this!!  The child health 
record is what parents carry with them from appointment to appointment and 
it has all the weights and the child's chart. The pages for recording 
weights have spaces for the date, the weight in kilos and the weight in 
pounds and ounces.  Usually the child is weighed in one and then it is 
converted (many scales do this).  Then the chart (our current UK chart is 
also in kilos) is plotted.  This dual system has already been running here 
for nearly 2 decades. 

Anyway, here in the UK we are *doing our own country design from the data*.  
Our chart *will not look like the WHO chart* -- oh, the curves will be the 
same, but the colour, the words on the page etc etc are what we are 
designing!!! 

As far as I know this is no problem for WHO. 

If the US wanted to adopt the chart, they could simply calculate all the 
weights in pounds and ounces and do their own drawing form the data.  It 
doesn't sound liek a difficult problem even to me, and I wouldn't tackle the 
mathematics myself. 

If this is really a serious reason, please please tell the people putting it 
forward this simple information!!! 

Maybe when our chart is done (it is due out in late March next year) the US 
committee that considers these things (assuming you have such a thing) 
should invite some of the UK people over to tell you how it was done. 

And I expect we will publish something, though currently there is simply no 
time to disseminate what we are doing.
