The letter κ always stands for the sound "k" in Greek. It is customary to transliterate (re-write) κ as "c" in English, but this is somewhat problematic since c is pronounced as "s" before e, i and y (which does not happen in Greek).
In mathematics, the lowercase [math]\displaystyle{ \kappa }[/math] is used to represent the curvature of a curve, while the uppercase Κ is used to represent an ordinal number which is also a cardinal number.[1][2]
