Not listing alternate units second, not converted on screen, not called “freedom units” and not hiding behind the excuse of “most our audience is in the US”
Mostly thinking YT channels like Wendover, Bluejay, sometimes Practical Engineering and even some European ones like TLDR News
The difference between a meter and yard is less than that of a measured vs “eyeballed” yard and everybody knows what 0 C and 100 C are so the learning curve is also massively (by at least 50 kg) exaggerated
First, What?
Second, why does the method of division matter?
Because if I’m measuring a board to cut, imperial divisions give me many more whole numbers that are way easier to deal with in most practical applications.
12 is divisible by 2, 3, 4, and 6, while 10 is only divisible by 2 and 5. That means that all of the most common divisions are straightforward to calculate, instead of me trying to guess how far between 3 and 4 on my ruler 3.3333333333 centimeters is if I want my 1/3 cuts to line up correctly.
That’s why the base of the system matters, and it’s why imperial is objectively 20% more based than metric.
In a duodecimal number system, metric would be absolutely gorgeous. We’d even have a metric unit circle: Each position on a standard clock would be represented by a single digit, and those positions line up with the most important angles in geometry.
Base-10 is the ugliest part of metric. 10 sucks.
Metric construction doesn’t start with 10cm or 100cm as a basic size. It uses a 600mm “module”. Dimensional lumber pretty much aligns with US sizes, not powers of 10 in mm.
And, are you telling me you can find an exact 1/3” on your ruler?
