Congress said it would confuse the old folks.

Depends on the old folks :-). I’m 78 and I’ll use whichever’s right.

I can deal with miles and kilometers, and I can handle kilograms and pounds, etc.

I prefer what I grew up with. If a cop stops me and asks, “Do you know how fast you were going, sir,” I’m not going to answer in kph. If I’m asked what I weigh, I’m not coming back with kgs.

If it’s hard, though, (really big or really small numbers, for instance), I might use my iPhone, my brand new iPad Pro, or my MacBook Pro to help out to save a tree.

Beyond that, I just pretend to be too old to f*** with it.

I don’t know your age, but I’ll bet you have 75% of an E6B’s functionality working all the time in you head.
