     Pyeongchang sits nearly half a mile above sea level in the northeastern corner of South Korea, not too far from the border with the North. It is one of the coldest parts of the country — wind chill in February is often in single digits (Fahrenheit) — and notorious for a powerful, biting wind that gathers force as it barrels down out of Siberia and the Manchurian Plain and then across the jagged granite peaks of North Korea.

   • 2021, Claire Cock-Starkey, Hyphens & Hashtags, Bodleian Library, page 142:

     For example, in the Fahrenheit scale 212°F is the boiling point of water.
