9k = 9,000

Hi, Tarah!

Kilo comes from the Greek "khilioi" which means 1000. That's why.

Oh, thats why, I had trouble with that too. Good to know, thanks Francis.

Thank you, Francis

Which becomes "kilo" in English and other languages, hence "kilogram" or "kilometer" for 1000 grams or 1000 meters. It is reduced for simplicity in some cases as in a 10K race which is an abbreviated way of saying a 10 kilometer race.

Outside the US & Canada, "gramme" and "metre" are spelled thus.

Sometimes people in metricated English speaking countries such as Australia, South Africa, New Zealand, India, in casual conversation, will call kilometres "klicks".
