I assume you're referring to centimeters (cm) and decimeters (dm). There is no plural for these designations for the meter. The story below appears to be a common American problem where decimals are referred to as fractions. Just dump the fractions.

Seeing the talks about keeping it simple has brought back some memories
of 5 high school math teachers in South Carolina, US.
The question that brought the 5 together was a simple question about CM(S) being written as 10 over 100 or even 10/100 and of course .01. The teachers all agreed that looked normal to them and went on to say that it could be written as 1 over 10 or even 1/10.
My response was to say that 1 over 10 or even 1/10 and .1 is DM(S).
The teachers one at a time tried to tell me that in math we round to the smallest possible number. Never did until that day had any of the 5 think that there was even a Deci. The rule of rounding filled the void as does it in the school books and even the minds of students alike. No is that any way to jump start the young minds that will need to know this metric stuff ?
! Don't take my word for it but I think that there is a breakdown that would be worth looking into.
Thanks for the looks and any comments about this, Tim
PS> Spell checker knows CM(S) and does not know DM(S) as it is written. Even spell checker is experiencing this void.
