2.7k is a standard resistor value.

Where have you seen 2k? It's not a standard value until you get to E96 series.

2.7k is really easy to find. I'm not sure that any of my local suppliers would actually stock a 2k resistor (even though they have 1% resistors that are E96 series)

tks steave. i was all ready to put two 1k in series to make that. Im glad that I asked.
he should have just put 2.7k
thank you very much.

1k5
2k7
5k6 etc etc is a VERY common and pretty much standard way of writing resistor values one character less taking up less space on what can often be full and complex circuit diagrams

the other very common way is just to use digits
1k = 102
2k7 = 272
5k6 = 562
10k = 103
100k = 104 etc etc

Also a bad copy can make the decimal point disappear, or someone (manually) copying it might change 2.7k to 27k. 2k7 is safer from both perspectives.
