I suppose you are referring to the later use, with the prefix replacing the decimal dot/comma. I have no idea if it is standardized by anybody, but it is in common use in EE. See, for example, the schematics on this service manual of a Nokia phone. You will see lots of components whose value is something like 3k3, 4u7 (4.7·10^-6), 1u5, 2u2, 6p8 (6.8·10^-12) and so on.

I suspect that this is as a safeguard against tiny dots "missed" in big paper sheets.

It also shortens the notation by one character. I don't know If I have seen it anywhere else than electronics and with resistor values. With magnitude prefixes you need to know the value of such prefix and with so called engineering notation (with magnitude steps of thousand) you need to know the correct prefix for a value.

While 3k3 style marking would be cool, I don't see much of an true value for it. Since anyone who uses such should be fluent of magnitude prefixes anyway, so 3.3k(Ohm) or 3.3e3 should be as clear as 3k3..
