Freedom as in "the freedom to drink your own gasolin in your home".

[-] AngryCommieKender@lemmy.world 5 points 11 months ago

Suicide is illegal in most states.

[-] intrapt@sh.itjust.works 6 points 11 months ago

Its a bit hard to get a conviction though

[-] sugar_in_your_tea@sh.itjust.works 3 points 11 months ago

It's one of the few crimes where you can only be arrested if you fail to actually commit the crime.

[-] butwhyishischinabook@lemmy.world 2 points 11 months ago

That's absolutely not true, you can be convicted of attempting crimes or for conspiracy to commit crimes.

Ukrainian drones now spray 2,500° C thermite streams

Looks like they turned up the heat.

Back to freedom units: 4532F.

[-] frezik@midwest.social 3 points 11 months ago

Significant digits of accuracy befuddles everyone.

[-] merde@sh.itjust.works 5 points 11 months ago

so you think that inches too is a freedom unit?

[-] shadowedcross@sh.itjust.works 112 points 11 months ago

I mean, it isn't metric, so yes..?

...being in nursing school is giving me a strong hatred for the imperial system.

The doctor ordered 35mg/kg Watdafuqenol IV QID. Available is a 2' by 15" section of torn out carpet soaked in spilled Watdafuqenol; when wrung out into the patient's left shoe, you get 97 chipmunk-mouthfuls diluted to a concentration of 24 Watdafuqenol to 1 toe jam. How many shot glasses full do you administer?

[-] proctonaut@lemmy.world 45 points 11 months ago

That's a trick question. How many pound-feet of torque did you apply to the carpet?

[-] Sterile_Technique@lemmy.world 25 points 11 months ago

1.15 pallets of spent 12-gauge casings over over the course of 2.3 standard breakfasts.

Yea I need a drink

[-] GiveMemes@jlai.lu 5 points 11 months ago

You might've already seen this, but try using the method of dimensional analysis where you work backwards on a single line and you'll never get one of those problems wrong again.

The key is just working backwards by units using the equations you have available. I know somebody that only got one of the questions on his MCAT correct bc he used this method lol.

[-] Sterile_Technique@lemmy.world 8 points 11 months ago* (last edited 11 months ago)

I use dimensional analysis, but it's over two lines... and not sure what you mean by working backwards, since the order doesn't really matter so long as every value is in the correct line.

Since typing it out would be ugly as sin, example image stolen from google:

...they like to give us things like pt weight in lbs and oz, and ask for final product of tablespoons or some shit cuz they enjoy wasting our time, lol.

That the type you mean?

I know there are a few different ways to crunch the numbers, but DA is my favorite so far cuz it's so consistent.

*edit, example pic changed, first one put mcg twice in the same line, which is a weird move. /shrug

[-] oldfart@lemm.ee 3 points 11 months ago

So USAnian drugs are in metric units? I hope in actual work nurses get to use a phone app or something because this asks for mistakes

[-] Sterile_Technique@lemmy.world 10 points 11 months ago

99% of it is metric. I think the biggest outlier is home care, where you go visit some grandma who's actively offended by metric, so if you tell her to take 7.5mL of something she'll just do the deer in the headlights thing, then shove the bottle up her ass.

Tell her instead that she needs to take 3 Mountain Dew caps full and suddenly she can follow instructions enough to not kill herself.

[-] ivanafterall@lemmy.world 5 points 11 months ago

Then she shoves the Mountain Dew bottle up her ass.

[-] prole 3 points 11 months ago

Yeah but that's for pleasure.

I thought everything is bigger across the ocean but your Mountain Dew caps are tiny over there! ;)

[-] Sterile_Technique@lemmy.world 3 points 11 months ago

Just googled it and apparently they're about 5mL each. Apparently I'm not great at eyeballing volume.

Add it to the pile of conversion failures between metric and imperial.

[-] oldfart@lemm.ee 1 points 11 months ago

Yeah, 5ml is a teaspoon, but I'm not sure if it's reasonable to assume teaspoons have similar sizes across countries.

But after your first month in the job you'll convert and eyeball it even when half asleep :)

Even in the US, science is mostly metric. But most US people are not exactly the scientific kind...

[-] prole 3 points 11 months ago* (last edited 11 months ago)

Until you start looking at old stuff and have you figure out if they were working with the "millions scheme" or "thousands scheme," and if "1 billion" is equal to 10^12^ or 10^9^

Modern science is, but there's plenty of old journals from the 80s and earlier that use degrees Rankine and gallons.

Fucking BTUs and shit.

PSI is another one that seems to be used over the metric/SI alternative in some science-adjacent applications.

[-] assassin_aragorn@lemmy.world 1 points 11 months ago

Psi is used a lot in engineering. But honestly, pressure units are a bit of a mess. The metric unit is a Pascal, which is fundamentally defined as a Newton per square meter – unsurprisingly, that is an incredibly small quantity of pressure. It’s roughly 101,500 Pascals for standard atmospheric pressure. You’ll typically see pressure written in either kPa, MPa, or bars (1E5 Pascals) within a metric framework. For perspective, it’s 14.7 psi (lbs per square inch) for an atmosphere.

And personally, I think all of these are pretty silly when we could be using 1 atm instead, which is literally defined as standard atmospheric pressure. It’s a much easier way to visualize and intuitively grasp pressures.

BTU is another fun one. It’s the energy needed to raise 1 lb of water by 1 degF. Calorie is the energy to raise 1 g of water by 1 degC. Both are very pragmatic definitions and have a degree of intuition. Then they’re the metric unit, the Joule, which suffers from the same issue as Pascal. It’s the work done by a 1 Newton force pushing an object 1 meter. Once again, pretty small.

[-] frezik@midwest.social 2 points 11 months ago

It works fine when everything around you is in those numbers. The scale for medications might be set to mg, or injections in mL. The bottles for both are labeled the same way. Everything works together, and you don't really have to think about it.

Part of the problem with converting everything to metric is it really needs to be everything. You can try talking about driving distances in km, and your gas tank in L/100km, and your speed in km/hr. However, the interstate highway signs will still be in miles, you buy gas in gallons, and the speed limit signs are in mph. This isn't a case where you can just choose to use the metric system as an individual, because the whole system works against you.

[-] oldfart@lemm.ee 1 points 11 months ago

That is understandable, I was surprised that metric is actually used somewhere. Use in pharmacy also explains why in Hollywood stoner comedies they used grams, which always confused me.

Even dimensional analysis works best with metric because sometimes you need to convert units and almost all conversion in metric are base 10, so something like 1kg/km is 1000g/1000m is 1 gram per meter. But in imperial 1 pound/mile is 16 ounces / 5280 feet is who the fuck knows how many ounces per feet.

Metric is excellent until it gets into data units. There shouldn't be a difference between 4T and 4TB, but it's actually a (1024^4^-1000^4^) ≈ 92.6G (99.5GB) difference because of the fuckers who decided to make data units metric and rename the base-2 data units to "kibibyte"/"mibi*"/"gibi*" (KiB/MiB/GiB)

[-] megane_kun@lemmy.dbzer0.com 15 points 11 months ago

I think the biggest mistake there is using SI prefixes (such as kilo, mega, giga, tera) with bytes (or bits) to refer to the power of two near a power of ten in the first place. Had computer people had used other names for 1024 bytes and the like, this confusion between kibibytes and kilobytes could have been avoided. Computer people back then could have come up with a set of base·16 prefixes and used that for measuring data.

Maybe something like 65,536 bytes = 1,0000 (base 16) = 1 myri·byte; ‭4,294,967,296 bytes = 1,0000,0000 (base 16) = dyri·byte; and so on in groups of four hex digits instead of three decimal digits (16¹² = tryri·byte, 16¹⁶ = tesri·byte, etc). That's just one system I pulled out of my ass (based on the myriad, and using Greek numbers to count groups of digits), and surely one can come up with a better system.

Anyways, while it'd take me a while to recognize one kilobyte as 1000 bytes and not as 1024 bytes, I think it's better that ‘kilo’ always means 1000 times something in as many situations as possible.

[-] michaelmrose@lemmy.world 3 points 11 months ago

There is no reason whatsoever to use base 16 for computer storage it is both unconnected to technology and common usage it is worse than either base 2 or 10

[-] megane_kun@lemmy.dbzer0.com 5 points 11 months ago

I guess? I just pulled that example out of my ass earlier, thinking well, hexadecimal is used heavily in computing, so maybe something with powers of 16 would do just fine.

At any rate, my point is that using a prefix system that is different and easily distinguishable from the metric SI prefixes would have been way better.

Everybody knew exactly what kilo mega and giga ment. when drive vendors deliberatly lied on there pdf's about their drive sizes. Warnings were issued: this drive will not work in a raid as a replacement for same size!!. And everybody was throwing fumes on mailinglists about the bullshit situation.

But money won, as usual.

Source: threw fumes!

[-] megane_kun@lemmy.dbzer0.com 2 points 11 months ago

Not too sure if they outright lied, but I suppose we can say that they used the change to make their drives seem larger!

That's why I wished computer people had used a prefix system distinct from the SI ones. If we're measuring our storage devices in yeetibytes rather than gigabytes, for example, then I suppose there's less chance that we've ended up in this situation.

I assume they call them freedom units because England freed so many nations. Otherwise... Not sure to be honest.
