For many other purposes, not.Example: F vs C temps. It just happens that 1° F is the smallest temp delta most people can feel. So for common purposes (turn the heat/water up/down) 1° C is too large a unit, 1/10 C is too small. 0-100 F covers a seemingly arbitrary range of below freezing to just above body temp, but it also happens, not coincidentally, to cover the range of temps humans can handle without high-tech clothing on the low end or cooling packs/extraordinary heat acclimatization on the high end. With Celcius I have to think "42 degrees, is that deadly heat or just beach weather??" In Fahrenheit, it takes no thought to understand the implications of 90F vs 110. Some of the other units are inconvenient, but each is more than a number counting how big is a thing; a grain, a dram a furlong each hold a bit of history. For example a furlong is the length of an average plowed furrow in the English common field system. So if you were to time-travel to the scene of the real Game of Thrones (roughly, War of the Roses), furlong sized things were part of daily life and possibly conflicts. Kilometers? They mean nothing, they're French. |
