@cpontvieux @LovesTha @mhoye @xek Kmph, while not official/scientific notation (as in notation encouraged by the SI) is apparently a widely used abbreviation. For example, see the link below.
It's potentially interesting (context dependent) to make people aware of SI conventions. Possibly not so useful to scold people on social media for employing widely used everyday alternatives in an "everyday" context?

(using a capital K at the start of a sentence is an awkward argument about which norm is more important)
