We were driving somewhere a few days ago and my wife asked why K means 1,000. I said I didn’t know and she said I should research it on my blog. So, here I am, researching it on my blog. I also wondered why K stands for a strikeout in baseball.
The explanation is quite simple. K stands for Kilo, as in a 5K race. I’m not entirely sure why K represents a strikeout, but at least the letter k is in struck or strikeout, so it’s not entirely random.
Additionally, kilo and strikeout aren’t the only things the letter K can stand for. Wikipedia has dozens more uses.
