Fahrenheit is not an arbitrary scale for when water freezes as it was not based on water to begin with. Rather it was based on the human body temperature being 100. Obviously they weren’t 100% correct. Also if we want to be facetious, Celsius is wrong too. We should be using Kelvin. Last thing to note is that Fahrenheit is a more precise scale than Celsius.
The US format on dates is similar to how I typically hear it spoken. So July 30th, 2019 rather than 30 July, 2019.
Also for some reason, I feel like the month is the most important. No basis on why, just feels that way to me.
