Kelvin use the same scale as Celsius, the only difference is the zero point. The imperial system and Farenheit sucks and result very expensive and cause even deaths because of wrong conversions: Crushed 2 Mars probes >$350M, flight crash with more than 130 victims because of an error calculating the amount of fuel, wrong amount of medicine respect bodyweight, etc..
The US doesn't use imperial, it uses US customary.
There's no US customary Roman mile, ell or skeine, for example.
Chains and links are basically standard surveyors chains. They're distinct units in their own right in the sense that a metric chain or metric link is. Should your metric chart have a metric chain on it? What about light years or parsecs?
Hands are used in measuring horses, and that's basically it. They're used in commonwealth countries, the US and South Africa.
I’m sorry, but Fahrenheit has nothing to do with the errors you cited. Hell, even the overall Imperial system, silly an (mostly) antiquated as it is, has nothing to do with the examples you cited.
The expensive failures you listed were caused by a lack of standardization. Those failures wouldn’t have taken place if every international agency had standardized on the Imperial system or the metric system.
Your point is not only a nonsensical non sequitur, it is also wrong.
It has nothing to do with standardization. With science and technology today, it is not possible to work in conditions with measurements and units random, based on parts of the body of a dead king centuries ago and not even, what is more serious, does not differentiate between weight and mass. Besides, it requires complicated conversions, a source of errors. For example of calculating the angular momentum in different parts of a 1.6 mile long bridge, if it has to be calculated with inches. No problem in a Bridge of 2,364 km to use Meters, centimetros or even Milimetros, only have to move the coma, no calculations needed.
The important thing in science is that the units are repeatable and reconstructible, which in degrees Celsius is not a problem, having as a reference the freezing and boiling of water at sea level as a reference. A similar reference for Fahrenheit does not exist, at least not with sufficient accuracy, which is why it was discarded as a unit. You can be sure that the manufacturers that supply Fahrenheit thermometers to the US calibrate them using Celsius or Kelvin, then put the Fahrenheit scale after converting the values.
Apologies, but I have no idea what you’re talking about.
Both Celsius and Fahrenheit are based off the exact same thing: the freezing and boiling points of water. Fahrenheit just gives you more resolution between the two (180 degrees for Fahrenheit vs 100 degrees for Celsius), but otherwise they operate in the same way.
I agree that the underpinnings of the weight and distance measurements used in the Imperial system are silly, but they are still just as accurate as the weight and distance measurements in the metric system. The metric system’s units for weight and distance are more logical and easier to use, but that doesn’t make them more accurate given modern measurement methods.
I think the US should adopt the metric system in general, but I honestly don’t see the point in bringing Celsius along with the rest of the measurement standards.
I honestly see zero benefit to Celsius over Fahrenheit: they are both pegged to the boiling and freezing points of water, Celsius was just unnecessarily limited in the number of degrees between those two points. Beyond that limitation of Celsius, there’s basically zero difference between it and Fahrenheit.
