kilometers
Yes. Theres kilogram, kilometer.....
You can basically use any letter for a constant. "c" is often used because it's the first letter of "constant"; the use of "k" probably arises either from the fact that it has the same sound, in English, as "k"; or from other languages where the word "constant" is written with a "k" (e.g., "Konstante" in German).
The letter K had no particular significance; it was chosen merely to have a phonetically different letter from the letters C and D.
