I think this note justifies aberrant US spelling. It takes two typos to turn deka- into deci-, only one in ROW. (I'm sure it is a typo as you had right twice.)
Apart from the meter/metre debate, the BIPM should take a 2nd look at this one. ________________________________ From: Pat Naughtin <pat.naugh...@metricationmatters.com> To: U.S. Metric Association <usma@colostate.edu> Sent: Thu, June 10, 2010 11:11:51 PM Subject: [USMA:47682] Re: Fw: Re: Oil Spill Technical Team Using SI On 2010/06/11, at 07:50 , John M.

By the way a cubic decametre (= 1 megalitre) – to an irrigator or a water engineer – is a relatively small amount. I suppose that an automotive engineer at the SAE might rarely meet with megalitres of coolant or lubricant so a cubic decametre might be an appropriate size. However, to an outsider the use of such a specialised unit smacks of jargon.
