Russian-languaged media is not commonly consumed by someone living under imperial/Fahrenheit system, so it's only natural.
For English, it might make sense to at least always add Celsius in parentheses, unless it's highly regional news.

Original article is about Asia, and Lemmy is an international platform, so neither applies here
I don't mind some actually regional things presented in whatever system they use in there - although I'd much prefer if we'd all go metric already. C'mon!
