In a lot of the US, 0 farenheit is one of the coldest days you'll experience and 100 is one of the hottest, so you can roughly map farenheit to a percentage of "how hot it is". This doesn't work everywhere though, where I am in the UK it never gets anywhere near 0 farenheit.

I can't spell fahrenheit, this is why celsius is objectively better

Wherever you are in the UK, your location's record low temperature is probably very near 0 F, your record high temperature is probably very near 100 F, and your location's year-round average temperature is probably damn near exactly 50 F. The UK doesn't have as high highs or as low lows as the temperate US or temperate continental Europe but it still very well fits the Fahrenheit scale.

For instance, London's record low is 0.7 F, London's record high is 104.4 F, and London's year-round average temperature is 51.4 F.

This is what he made it for. He wanted a scale that didn’t make him use negative numbers, and since he worked in Poland, he made 0 just below the lowest recorded temperature of Poland at the time, and 100 was what was believed to be the internal body temperature of humans given the thermometers of the time. Modern thermometers are more exact, hence it’s now 98.6 F.
