By the way, calculating on base 16 (or base 12 or whatever) is just as easy as calculating in base 10, once you get used to it. Some of the programmers here probably can think easily in base 2. This doesn't connect to distance travelled or amount of fluid to be purchased, it's just a self-contained mathematical model.
This self contained mathematical analogy is no more visible than in cost accounting. Example, a fixed cost for the amount of energy expended to travel a specific unit of distance can be calculated using either system. Either mathematical model can be used to reconcile out of pocket expenses for these energy units per distance units. The cost doesn't change, just the units.
Likewise, in the past decade or two, industry has adopted either both of these mathematical models for diversity, or the metric model exclusively within their own products. Especially those industries that trade or depend on metric influenced technologies and nations.
The problem however, or this reluctance to throw the old mathematical model completely out of the window, is simple, cost. Older and existing systems, technologies, and designs carry a heavy expense to redraft work orders, retool, redefine specifications, quantify quality assurance, litigation oversight, and (purchasing) governance, when these systems are mission critical, life support, or just utterly expansive and encompass many industries or technologies within a particular infrastructure or system.
On a smaller scale, I recall a teacher in High School answering a fellow students question regarding the usefulness of algebraic theory in our daily lives outside of the class room. His answer simply stated that some folks will need this mathematic theory in their jobs. For decades following High School I plotted 2 dimensional and 3 dimensional coordinates for computer numerically controlled machining centers using a calculator and a pencil. (yes, the slide rule had already been obsolete by the pocket calculator) But I never forgot this instructors wisdom and to his credit I made a comfortable living because I listened.
Low and behold, a few years later we (the industry) had to absorb a new mathematical system to utilize the metric system that was already ingrained in our computer controlled equipment along with the older mathematical system so that we may (ultimately) compete on a wealth of new contracting opportunities.
IMHO, environment, commerce, and industrial trade will eventually bring about this accepted change and standardization. Useful employment and the removal of remaining obstacles (stubborn industry leaders as well as the occasionally stubborn employee on the plant floor) will guarantee enthusiastic acceptance and understanding.
