That's 113 degrees Fahrenheit for American readers. The rest of the world has wisely adopted more rational measurement units. Even Canada, a stone's throw away from the U.S., uses the Metric system.

Sorry, mathematician joke.
The way Farenheit got to his scale seems really less practical to me, from Wikipedia :
"Fahrenheit proposed his temperature scale in 1724, basing it on three reference points of temperature.[9] In his initial scale (which is not the final Fahrenheit scale), the zero point is determined by placing the thermometer in brine: he used a mixture of ice, water, and ammonium chloride, a salt, at a 1÷1÷1 ratio. This is a frigorific mixture which stabilizes its temperature automatically: that stable temperature was defined as 0 °F (−17.78 °C). The second point, at 32 degrees, was a mixture of ice and water without the ammonium chloride at a 1÷1 ratio. The third point, 96 degrees, was approximately the human body temperature, then called "blood-heat".[12]"
Reproducible if you happen to be near sea level.
For distances, a person's height is measured in feet and inches, tailors prefer to use inches for their dimensions, plots of land are often measured in feet. But everything else is metric. (Listen to the local farmer speak, in your own vimeo video link.) Speedometer, odometer, fuel, grocery, produce, etc. all use the metric system. To say nothing of my entirely-metric work in engineering.
It seems like, as with the examples you give, that certain systems are used for certain purposes which was always fascinating to me come from outside. In construction, in rural areas I've found it varying between different parts of the country whether metric or imperial is preferred.
