Why are these resistors marked as such? Answered

Hi, I ordered a kit of assorted resistors (112 types, 10 of each), and it's awesome, however, some resistors are marked weirdly, like 1k8, 2k7, 1m8, 2m2, there's quite a few. What's the meaning of these?

It's unusual to see resistors marked like this, but it's quite common practice to refer to a 2.2K resistor as 2K2, a 5.6M resistor as 5M6 etc.  The letter replaces the decimal point and indicates the multiplier.
K is times 1000, M is times a million.

The other one you might see is e.g. 4R7, which is 4.7 ohms.

Ok thanks, for lower ones though they do use a decimal point.

As Andy says, its to avoid confusion of the decimal point.
