We created the units of measurements (notes / volts / whatever) through observations - we define and name them like ticks placed on the ground every 10’ when walking a mile at a steady pace. Next, some time goes by and we forget the times we we did not have these ticks on the ground defined. Now we devise a wheel to count the ticks. Then we sit back in an amazement and wonder about the serendipity of it all - how could this measuring device perfectly line up with these units of measurement. Well we defined both puzzle pieces - so of course they fit together.
There may be reasons to have faith, but I do not believe this is a very strong one. If there was a higher power and they had a hand in electronics, WE 300B’s would grow on trees like oranges and I wouldn’t have to consider skipping a mortgage payment to get a pair.
