   • 2019 February 28, Lindsay Denninger, “Why You Might Be Wrong About Emma & Barbara Morgan On 'Million Little Things'”, in Bustle‎, archived from the original on 29 March 2023:

     She stalked the family home to catch Sophie on a run, and then she lied and said she was a part of the 5K the family did in Jon's memory. Then, she wanted to leave a note (or maybe the memory card with that info on it) for Delilah, and then she chickened out. These aren't actions of a straight-thinking woman.

2. (computing) A display device or item of content with approximately 5,000 pixels in the horizontal axis.

使用する際の注意点

When written in its expanded-out form, "5000 metres" typically denotes that the race is run on a track, as compared to 5K, which denotes the race is run on a road.
