Doing drone thrust/HP calcs and am ensnared in this LOL!

Gee, always liked the non-SI units.

Don’t mind science having a little fun with me (after all, it’s even older than I am) but WTF?

You mean the Imperial system?

On the earth’s surface, one slug = 32 pounds. Just like one kilogram = 9.81 newtons. (Just to compare mass with weight on our planet’s surface, because both one slug and one kilogram weigh nothing in space.)

OK, my head is swimming after that. Trying to figure whether this satire or not?

Walked out into my shop one day one of my workers was sitting on top a 18 wheeler airspring and fix'n to hit the intake with a air nozzel.

We had a 200 gal, 200 psi, 440 volt compressor, 2" plumbing for air routing and a 1/2 in fast fill air hose.

Stopped him and got my pocket calculator out.

Standing next to him we calculate the surface area of the top of the airspring, guessed 1/2 flow of the air discharge of the air gun, the lbs of force that would be exerted to the top of the airspring and his weight...

He would have shot almost 25 ft into the air.

He declined to continue his misadventure quest.

He uses the abbreviation of “sg”. When I see “sg” I tend to think in terms of “specific gravity”.

So, it’s possible to have a slug of salt?

Oops, missing a parentheses => https://en.m.wikipedia.org/wiki/Slug_(unit)

I had physics and two years of algebra in high school, and after reading that, I feel like those courses were a complete waste of time.

I thought British people measured their weight in stones. Do their scales actually show pounds?

Wow, don’t know why that end parentheses is not copied when I pasted it. Just type it in.

I love the slug. My wife and I had a blast firing off the 12 ga and 20 ga kind last night.

I was shooting slugs at the range. No not the garden slugs either. These were Remington shotgun slugs weighing 437.5 grains as if slugs as a unit of measure was not obscure enough.

Years of physics and engineering study in the 70s and 80s; I never had to use the slug. Pounds-mass and pounds-force. You just had to know that one lbf equals 32.174 ft-lbm/s2. The “slug” is a derived unit to make one pound force equal to one of something.
