Should it be DECA or DEKA or both?

IMO: Might as well include all the prefixes up to 10**24

And how do people avoid using MILLI for KILO, MEGA for MICRO, etc...
The compiler won't care but usage could look odd.
I find this patch creates more confusion than solves a real problem
(typo where one zero is missing or one extra) and adds potentially
needless churn. For instance I don't assume much use for the HECTO now
or in the future.
How about if absolutely necessary just adding only KILO, MEGA and GIGA
and questionable defines only after when the real needs arises and can
see does "1/1000L" etc define cause any troubles to real calculations?
