With regard to semantics, I would like to mention the use of the comma as decimal separator. I am sure that most of us are aware that comma "," is used to separate integers from the tenths in Europe as opposed to the period "." which is used in USA. Thousands, Millions, etc. are separated by a space as opposed to the comma. Mechtly has separated the thousand in the European manner.
When I purchased nuts for my honda recently it was labeled as: M8-1.25, but the bolts I used to test the thread were labeled as: M8-1,25. Does SI specify the punctuation as to the decimal and thousands separators? On 1/27/09, [email protected] <[email protected]> wrote: > > Aaron, > > Agreed, the ton is a unit of mass.
