Actually, I use radians all the time. Probably one of the least recognized, but common, uses is in firearm scopes. My Falcon Optics M18+ 4-18-44 is mil/mil. WAY easier to scale than MOA. I have been metric for decades. Went that way in the 70s, and never looked back. Had to go to Canada to get my first metric tape so that my ham measurements were easier. I use metric in everything...including the table that I made. https://drive.google.com/file/d/1-kXMx8i1qiBQSUYgWUzdP9isucuOCopv/view?usp=sharing Not only are the measurements metric, but the table has nearly 100 unique angles. All my woodworking buddies said that it was not possible to make a table this accurately. Picture attached, because it's hard to describe. I use decimal angles for those. Yep. You can really cut an angle of 10.3 degrees on a table saw. I'd have been just as happy w radians (remember those mils), but couldn't find a miter in radians. I use degrees because I am comfortable with them, but the same goes for radians. Fer us hams, 2 pi rads/s is 1 Hz. Grads have their place, but I don't see them catching on. Geometrically, degrees make sense, as do radians, but grads, to me, grads have more "people intuition" sense...just not popular. Ya gotta admit that grads are easier than adding and subtracting from 360 if you're on a hike. At that, radians would also be easy, as long as you don't mind 2pi ;-) Finding a reverse course, pretty easy; right angles, not so much ;-)
