look up any word, like bae:
 
1.
2k5
2k5 stands for "2005", because k stands for "multiply by 1000"

I disagree with dkkev, 2k5 means 2500.

k stands for 1000 indeed, 1k is 1000. But the k is put on the place of the dot to shorten the notation. So 2k5 actually means 2.5k
It's mostly used in the notation of values on electronical components, like Condensators and Resistors.
Give me a 2k2 resistor.
