No kidding. It ain't rocket surgery.

Of course not!

It's brain science, silly person!

Of all the things I wish the US would just do that's near the top of the list.

I'd be fine with losing everything except Fahrenheit.  It's much more useful than Celsius.

Jesus Farking Christ on a Crutch.

Yet another way this country manages make itself an international laughingstock - and over simple, no-brainer stuff, too.

Have to check in with my buddy Mike the surveyor.

People keep saying that, but it never goes beyond "cause it is what I'm used to".

They have. Years ago.

According to TFA, the American Foot is defined as a fraction of the International Metre.

D'oh...

That doesn't make it a metric unit.

Lovely. A cumulative rounding error. The international foot is defined explicitly as 0.3048 meters, or twelve explicitly-defined international inches (0.0254 meters).  The survey foot is derived from twelve inches divided by one meter (expressed in inches rounded to two decimal places; the meter/inch ratio is defined as 5000/127, or 39.3700787401575 inches). That would be 1200/3937 or 0.30480060960122 meters.

The diameter of human hair varies from 0.017 to 0.18 millimeters (0.00067 to 0.00709 in).

Splitters.

The ONLY way the imperial system is even remotely functional is to map it to the metric system and brainwash people into thinking it's still necessary. The inch is 25.4 mm. If someone is using a foot that's not EXACTLY 304.8 mm they deserve to be beaten to death with a shovel. It is negligent beyond belief to not be using correct units.

Thing is, the metric system came about because every country had a system like this:

So, it's obviously better to do away with all your systems of weights and measures based on the size of the King's toe, or however you figure it out, and develop a system based on actual precise measurements.

The only thing that allows America's Imperial system to make sense is that the rest of the world gave up on such silly measurements.

/And regarding temperature, no matter which scale you use, you're going to be using decimal fractions for accuracy, anyway, so it ends up being about your feelings.

Two points included in the article. 1) " The two are nearly identical-dividing one by the other provides a ratio of 0.999998" and 2) "But Dennis notes that this does happen, citing an engineer's account of a building that was constructed near a landing strip-and had to lose its top floor at the last minute to avoid obscuring the planes' glide path, which had been calculated with a differing type of foot."

How tall does a building have to be that a .999998 ratio difference can cause a building's height to be outside the tolerance of obscuring a planes guide path?

10,000 ft x .999998 = 9,999 ft 11 3/4 in. I call bullshiat.

You're assuming the error was the height of the building. The error was likely the position of the building.

Fair enough. The difference per mile is 1/8". It seems like an excuse, "it's not my fault the building is too high, it's those damn feet and inches."
Disclaimer: I don,t like building in metric. Millimeters are so close together that when reading the tape it's hard to mark 4mm. It's easy to mark 1/8, 1/4, etc. And with metric the numbers are bigger,  2400mm vs 8 ft, (38 x 89) vs (2x4).
Yes, for engineering purposes metric is great.

You don't understand surveying at all. They don't take a big tape measure and go from point A to point B and call it a day. They measure lots points. All of those errors add up. With every single measurement that error compounds. The error in the measurement itself is bad enough, but those are random, both plus and minus. A hard coded error in every calculation is another matter. A building could be out by a hell of a lot more than 1/8". The errors end up as having major consequences like "whoops, our buildng is over the property line".
