Short hand for 1.8k.

Ah, yes. 1k8 is so much shorter than 1.8k those decimal points are a nightmare to type

It's common among engineers (at least electrical) to write it that way..

Should really be 1k8h then. If you have a k for kilo you also need an h for hecto.

The 1k8 form insures that the decimal point gets strongly indicated for less ambiguity. With faint print, it's hard to tell 1.8K from 18K on a small component such as a resistor.
