Metric is excellent until it gets into data units. There shouldn’t be a difference between 4T and 4TB, but it’s actually a (10244-10004) ≈ 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)
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.
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.
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.
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
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.
I realized why I didn’t think of base 2 in my previous reply. For one, hexadecimal (base 16) often used in really low-level programming, as a shorthand for working in base 2 because base 2 is unwieldy. Octal (base 8) was also used, but not so much nowadays. Furthermore, even when working in base 2, they’re often grouped into four bits: a nibble. A nibble corresponds to one hexadecimal digit.
Now, I suppose that we’re just going to use powers of two, not base-2, so maybe it’d help if we do a comparison. Below is a table that compares some powers of two, the binary prefixes, and the system I described earlier:
Each row of the table (except for the rows for 210 and 250) would be requiring a new prefix if we’re to be working with powers of 2 (four apart, and more if it’d be three apart instead). Meanwhile, using powers of 16 would require less prefixes, but would require larger numerals before changing over to the next prefix (a maximum of 164 - 1 = 216 - 1 = 65 535)
One thing that works to your argument’s favor is the fact that 1024 = 210. But I think that’s what caused this entire MiB vs. MB confusion in the first place.
However, having said all that, I would have been happy with just using an entirely different set of prefixes, and kept the values based on 210.
People weren’t using them ambiguously, drive manufactures picked a non-standard unit to lie with on their boxes, and then tricked courts into going along with their shit because it was the old case of money vs truth.

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 tow jam. How many shot glasses do you administer?
You’ll never see dosage questions like that on the NCLEX. If you do it’ll be like one. I breezed through it when I took it, but basic knowledge questions are minimal (as long as you don’t get them wrong).
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.
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.
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
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 1012 or 109
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.
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.
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.
2,204 degrees Celsius in non-freedom units
Thank you for posting it in normal.
Looks like they turned up the heat.
Back to freedom units: 4532F.
Significant digits of accuracy befuddles everyone.
so you think that inches too is a freedom unit?
I assume they call them freedom units because England freed so many nations. Otherwise… Not sure to be honest.
I mean, it isn’t metric, so yes…?
how many fingers do you have on your 2 hands?
feel free to count
~24 inches of fingers.

They could have easily used base 2 which is actually connected to how the hardware works and just called it something else

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

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

I thought everything is bigger across the ocean but your Mountain Dew caps are tiny over there! ;)
Then she shoves the Mountain Dew bottle up her ass.

That’s a trick question. How many pound-feet of torque did you apply to the carpet?
1.15 pallets of spent 12-gauge casings over over the course of 2.3 standard breakfasts.
Uhhh 6? Ish?
Don’t forget to round to the nearest liquor store!
Yea I need a drink
yep
2,204C is for those in Boca Raton and Rio Linda…
Freedom?
Freedom to merc your classmates at school
Hell yeah 😎 🇺🇸
Freedom as in “the freedom to drink your own gasolin in your home”.
Suicide is illegal in most states.
Its a bit hard to get a conviction though
It’s one of the few crimes where you can only be arrested if you fail to actually commit the crime.
That’s absolutely not true, you can be convicted of attempting crimes or for conspiracy to commit crimes.
