With nuts and bolts it doesnt matter that much

13mm = 1/2"

15mm = 9/16"

"K" is frequently used as an abbreviation for "thousand," but kilometer is "km."

Commonly and incorrectly. Technically speaking, lower case "k" denotes "kilo" (thousand), while upper case "K" is reserved for Kelvin, a measure for temperature.
