So far there is no official prefix for 10^27. If they follow the current pattern they will start with nona, decide that Nm is too ambiguous (nonametre or Newton metre) and that nm is already nanometre so go for xona (X) for 10^27 and xono (x) for 10^-27. They could just as easily go Greek and select xenna and xenno. I hope they spilt the difference so we can have Xena and xeno.
Actually ... come to think of it, watch this space ;-)
