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
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
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.
I thought everything is bigger across the ocean but your Mountain Dew caps are tiny over there! ;)
Even in the US, science is mostly metric. But most US people are not exactly the scientific kind…
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
Modern science is, but there’s plenty of old journals from the 80s and earlier that use degrees Rankine and gallons.
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.
