Since we all have these fancy-schmancy computers now, it would be nice if the computer could automatically translate these numbers into your preferred system. Something for the next version of HTML, maybe. Of course, to make this really painless, we would need a sophisticated parser that could identify the numbers and units being used. Should be a piece of cake for the people who brought us self driving cars.
The drawing above is supposed to show that the Metric system is superior to the English system, and if the world was filled with rectangular islands it might be. But it's not. The world we live in is more like the squiggly shaped yellow island. The English measurement system has been constructed to measure the world as it is. For science and engineering, the metric system has certain advantages. Given a choice, I would prefer to work on cars built using the metric system. Fractions of an inch are just a pain. They would be okay if they stopped at sixteenths, but no, so people insist on using 32nds, and even 64ths, and then below that they revert to thousandths of an inch.
For things in everyday life, like weather, land, travel and houses I prefer the English system.
