I'm currently studying for the PE exam and part of the rear end in a top hat nature of the thing is I have to know how to do every problem in every type of unit. It's not too bad for most problems, but lbs-force and lbs-mass is just I never know when to properly use the conversion, and why am I doing poo poo outside of a gravity well and then skewing for Earth's gravity any-loving-ways.

Darchangel posted:A "cup" is a unit of volume measure = to 8 fluid ounces, or 236.6 ml. What's so hard about that? It's a standardized unit, just like liters or whatever. Yeah but the poo poo you are cooking can often vary in volume by ingredient. Going by weight straight off gets you what you need.

Nobody cares about the ambiguity of motherfucking GAS MARK as a measure of heat?

For some people it's close enough, whatever floats your goat. E: gas mark is retarded we agree. Electric ovens are better anyway

CAT INTERCEPTOR posted:Being ignorant of Imperial is a good thing. Your country should try it sometime and join the rest of the world just a few things "metric horsepower": DIN 66036 defines one metric horsepower as the power to raise a mass of 75 kilograms against the earth's gravitational force over a distance of one metre in one second;[18] this is equivalent to 735.49875 W or 98.6% of an imperial mechanical horsepower. the metric countries can't even loving agree on an acronym for it, there are SIX DIFFERENT ONES (PS, cv, hk, pk, ks, ch) and ANSI vs DIN vs JIS metric bolt heads get off your high horse before I shoot it Adiabatic posted:I'm currently studying for the PE exam and part of the rear end in a top hat nature of the thing is I have to know how to do every problem in every type of unit. lbf vs lbm is the worst drat thing, but at least being off by a factor of ~30 is usually a hint, unless you're just working with staggeringly huge or tiny numbers and can't get a good feel for it. If lbf/lbm is involved I usually convert all my poo poo to metric and do it in metric then convert back as a sanity check. kastein fucked around with this message at 16:48 on Feb 16, 2017 |

My metric/imperial nightmare is happening at my new job. The edict has come down that we should do the entire machine in metric fasteners. Which is fine. Except for once in a while like when I want to buy a gas spring or something like that, that only comes in imperial threads on the end. Yeah I could shop around all different suppliers until I find one with metric threads but we're a small company, and that just adds to hassle and lead time that we really don't have time for. So my machine is about 99% metric with maybe 8 imperial fasteners in it. Then we ship them to old school unionized factories and when they lose a bolt they end up having to run out and buy one and get pissed at us because their tool room doesn't stock anything in metric. I first went to college in 1989. They taught us everything in metric and imperial because we'd be switching to the metric system "any day now".

It's slightly less schizophrenic here. Dimensional lumber and construction is all done in imperial. Recipes are almost always in imperial, even the ones printed on packages (which I imagine pisses off Quebecers to no end). Everything else is metric. Older people here used to tend to use Fahrenheit when hazarding a guess at the ambient temperature, though less so now because Boomers and Gen Xers have figured Celcius out finally.

Random question for you guys. What's your preferred brand of heat shrink and crimp connectors? I'll be using deutsch (if I can find the $$$ tool to borrow) or weather pack for most of the connections but there's going to be enough tab and crimp connections I'd like to get some that are tested and not poo poo.

BraveUlysses posted:what? fireworks are legal all over the US In Ohio, you can buy small things like sparklers at Walmart. There are specialty fireworks stores that sell bigger ones but it's illegal to set them off in Ohio. You're supposed to leave the state with them within 24 or 48 hours.

Yes but mpg directly links to my dollars, which is easier to convert to "commute dollars" in my mind. "This car gets 20mpg. My commute is 18 miles. It takes one gallon of gas to get to work every day. That's four gallons a week." Or "I have $5. That's 2 gallons of gas, which is 40 miles. I'm poor as poo poo, so this weekend, I can drive 40 miles on what money I have. Both make "intrinsic" sense to me. It's probably just because I grew up and think like that . Versus "Okay, my commute is 36km. My car gets 10L/100km, so 100 divided by 36 and blaaaagh I don't care anymore division is hard. Do I have enough money for the week's commute? I don't loving know." E: you're right that it's straightforward, but it is one more number to remember.. Just one, but man that extra constant, and two steps in the process, is so much to get people to convert over. MPG method: commute is X miles, car goes Y miles per gallon. X / Y = Gallons needed. L/100km method: commute is X km, car needs Y liters per 100km. 100 / Y = Z. X / Z = liters needed per commute.

My commute is 35 kilometers each way, so I'll need to fill up on my way home, the day after tomorrow." It's actually pretty straightforward, but you're right that MPG is probably just ingrained in your mind from so many years of using it.
