Where in Europe do grandmas talk in Fahrenheit?
gpt
In the past. The UK moved from Fahrenheit to Celsius in the 60s for weather reports and then adopted metric currency in the 70s. But Fahrenheit remained as a secondary measure in weather forecasts for decades, probably well into the 90s. Older people would use 100 degrees as a way of saying the weather was really flipping hot.
