SASless,
But then.....being the big boy on the block when it comes to building things....I guess we can get away with it. That is not being arrogant....just realistic
But what about big mistakes, like not making the conversion when grinding the mirror on the Hubbell telescope?

Dave....show me a perfect system that eliminates human error...just one. The British had the Titantic....watertight compartments that did not have bulkheads clear to the overhead thus water could spill over the top into the adjoining compartment. NASA and the Shuttle....lots of problems there....auto makers recall cars....airplanes and helicopters have AD's issued....God made the pit in the Avocado too big....it just is not a perfect world.

I think the US Gallon is a clever unit

at 15C ~ 60F

1 USG Avgas weighs~ 6Lb

1 USG Avtur weighs~ 7Lb

Makes it easier for my zums

Yes, but why, when Americans usually make things bigger, did they make it smaller??

During one of those very long evenings watching a bunch of hicks turn left (or NASCAR as everyone else knows it) the penny dropped that the US Gallon is based on 16 FL OZ to the Pint instead of 20 FL OZ, just like the Brits insist on 16 Dry OZ to the pound, hence the 25% overmeasure, or under, depending on your origin. Seems perfectly logical when you look at it like that.

They did inherit Imperial from the Brits, but they have just decided to stick with this particular habit. Mind you, a bloke finishing his pint, sticking a couple of gallons of petrol in the car and driving a few miles home to eat half a pound of bacon in a sarnie, and then complaining about the US fixation with Imperial units seems a touch ironic.

The ultimate gotcha has to be the Canadian early 767 some years ago that loaded Kg's, failed to display Lb's, dipped the tanks in inches, fudged the conversion and eventually became a really big glider. They all walked away, but I bet the crew had a sharper appreciation about standard units of measure after that.
