Lb-Ft
FFS, just adopt the metric system already. And “lb” is not a force unit. Also don’t capitalize unit abbreviations unless named after scientists.
Actually pounds are a unit of force
Pounds~newtons
Slugs~ kilograms
Pounds are a unit of money.
lbf
(poundforce) is a misnomer, it’s actually the pressure required to stamp the King’s portrait into a £1 coin. Slightly changes with each monarch – or by a lot whenever they switch to cheaper materials because of devaluation. The frequent redefining of poundforce is now a major consequence of Brexit. /s
Mercifully, g=9.8 everywhere on Earth’s surface, so we use weight interchangeably with mass, but yes, we should weigh ourselves in Newton: “I need to lose 10kg, so I can reach my ideal weigh of 700N” :P
Mercifully, g=9.8 everywhere on Earth’s
Big nope. It depends not only on height, but also on density of stuff under ground.
I’d say it’s more of a “small yes” than a “big nope.”
While gravity does vary, it goes from about 9.76 to about 9.83.
All of which does, in fact, round to 9.8
On ISS it’s 8.722, but it’s constantly falling.
Everything experiences different gravity (and “apparent gravity”) in space. We should pass a treaty of using metric only there, if only to avoid losing more spacecraft.
We already have a permanently inhabited base outside Earth (ISS) with effectively zero gravity and there might be one on the Moon or Mars in 100 years. We should pass treaties to only use metric in space – a probe has been lost to unit confusion already.
On ISS it’s ≈.89g, but agreed
I said “effectively zero gravity” for a reason – the term is “zero gravity” but I know it’s a misnomer.
This is dated 2007. Apparently NASA is already using metric:
I know, it has always used metric but the SW was by Lockheed Martin. Still, we need to convince potential extraterrestrial civilians.
As someone who’s all about science and all the things that use metric as it’s standard, I understand why us Americans argue for imperial measurements.
We know them.
I can general look at something and relatively tell how big it is based on my experience with the imperial system.
I’m not saying metric isn’t better but there’s also different languages with some of them being able to express certain emotions or features better than others. Yet you don’t see people demanding we all adapt a singular language.
You should start by adopting metric in anything remotely scientific. Like
- voltage ✔️
- current ✔️
- power ❗ - horses are no longer really relevant, not to mention this - at least appliances use watts
- pressure ❌ - we got lucky that 10⁵ pascals is around 1 atmosphere so use
Pa
orbar
, notmmHg
orPSI
- BTW,
PSI
is a dumpster fire of an abbreviation, the correct one islbf/in²
- BTW,
- force ❌ - the
lb
/lbf
confusion is not worth it when we have newtons - energy ❗ - joules and watt-hours are both fine, calories, electronvolts and TNT-tons less so, but don’t use
BTU
which nobody can really comprehend, or gasoline-gallon-equivalents that nobody knows how to translate to anything else - gun caliber ✔️
- engine volume ☑ (it’s
cm³
orml
, notcc
FFS)- strange that motorcycle and gun enthusiasts are the few users of metric length & volume measurement in the US - too bad that these two measurements are never really used in calculations or conversion
- torque ❌ - this post says
Lb-Ft
which is wrong on so many levels - data ✔️ - OK but data rates should be abbreviated
MB/s
orkb/s
, notkbps
,Kb/s
,kbit/s
orMbit
- wire diameter ❌❌ - holy shit, AWG is such a mess - larger wire is smaller number and the formula is so insane that people use lookup tables, also you’re afraid of decimal or negative numbers so large wires are 00, 000 etc.
Can you imagine having different units across the world for voltage or data? Like a 2¾-lemon battery or a 2 million floppy hard drive. That would be absolutely insane.
There is an awful lot of inconsistency in the imperial system too, like pound being abbreviated
lb
,P
(inPSI
) or even£
, or miles beingmi
orM
inMPH
About torque though: If my memory doesn’t betray me, one Newtonmeter is 100 grams hooked to a one meter long lever. Is that really different from one pound hanging off a one foot lever? I might be wrong, since I was born metric and have no clue in general.
It’s 1 Newton at 1 meter.
As simple as 1 pound at 1 feet to be fair, the bad part is that pound is used as a measure of force as well as of mass. It works on the surface of the earth but not anywhere else.
Pounds are a measure of force, not mass. The imperial unit for mass is Slugs
I wonder what you’ll get when you ask for 0.02 slugs of ham at a butcher’s. Probably nothing but a horrified look.
Recommended units for data have been mibibytes (MiB), gibibytes (GiB), etc. for a few years now
They’re more accurate because they use powers of two (actually 1024 instead of 1000)
“Accurate” is probably not the correct word anymore. It was when technical limitations dictated power-of-two capacities. Commodore 64 came out with 64 kiB = 216 B of memory, and FAT32 cannot handle file sizes ≥4 GiB (232 B). However, RAM/ROM/Flash chips manufacturers no longer make exclusively powers-of-two capacities, instead opting for (decinal) GB to save 7 % of the cost (and other fake capacity shenanigans). I prefer binary too but the two unit systems can coexist, people just need to label them correctly.
You acknowledge what they really mean is ft lbf right? Usually pronounced foot pounds. It’s a common unit of torque in the imperial system. I feel like people are just jumping on the bandwagon. This is coming from a diehard Nm preferrer, we need to choose our battles. How bout we die on the hill of bite force being measured with units of pressure? Like really? Fucking pressure? Utterly meaningless as a unit of comparison between bite strength of animals, since all you need to get a bigger number is SHARPER FUCKING TEETH.
Yeah, you can make really great pressures easily with sharp things, making an atomically sharp point is surprisingly easy.
But my favorite hill is this.
It’s confusing, since “pound” is used for both force and mass.
1 lbm is roughly 0.45 kg
1 lbf is the force required to accelerate a 1 slug (32.2 lbm) mass 1 ft/s^2.
I don’t know what the imperial system standards committee was up to, but I’ve never met a slug that was 32.2 lbm
lbm
What a brainfart of a unit is that?
If you don’t know what this is about, don’t google the Name of the vehicle at work.
Actually, neither duckduckgo nor google nor bing nor startpage nor searx yields anything besides XBus formerly known as eBussy for me. So, if this name is somehow funny somewhere in the world, google & co are not helpful.
Bussy aka Boy Pussy is a way of referring to a literal male asshole when you intend to use it for anal sex.
TIL… Still a good name: Using our new Electric BUS SYstem is as much fun as using a bio-bussy! would be a great slogan…
Try it without the “e”
Ok. Meaning kiss on the cheek in German? And?
20hp
737lb-ft torque
Sweet Jesus Christ.
That’s more torque than a lot of modern muscle cars have. I know electric motors can shit out a lot of torque, but holy fuck.
The ebussy needs a lot of thrust
