The USA and Burma.How many countries still use imperial?
I get annoyed with Budweiser, it is because one bottle of Bud (330ml) costs the same as a pint. Two bottles of Bud fill a pint glass. It's all I drink when I go out so I'm pretty good on this particular brand. I would love to see a pint of Bud. How big are the bottles out in the US? (in ml please so I can compare). We can get 250ml bottles here, but I never see the point. All pubs serve 330ml bottles. And as before, two bus to every (British) pint.The USA and Burma.
Just to add to the confusion the American call feet/inches 'English' units but they are sometimes different from the English 'Imperial' units. A US pint is smaller, because you wouldn't want to have to drink 562ml of Budeweiser.
This also annoys the Scots and Welsh - so can't be all bad!
Wrong thread, wrong argument.I'm glad that NASA decided not to waste the estimated $370 million that it would cost to convert units.
I wish I could say that I hope the money they saved is well spent towards space exploration, but NASA has long ago abandoned that dream...it's no wonder the government has repeatedly slashed their budget.
Somewhere between the space race and now, the higher ups over there decided that accountability is more important than space exploration. If you ask me, there is no more honorable calling than exploring the nature of the universe we live in. This does not mean sending repeated shuttle missions to the same space station for god-knows-what.
I want to see a colony on mars in the time it takes to travel to the moon + the time it takes to develop the technology - the date we started thinking about it. That means we should have been there years ago. More likely, none of us will live to see the day. Pathetic!
They seem a little confused about that:A lbf is force and a slug is mass.
Ooh yeah, that post above, WEIGHT AT TAKEOFF and then it is quoted in KILOGRAMS.It should read, errrrrr edit: Newtons.
So actually, its you people around the world calling everything 'kilograms' that's the problem. Start calling it what it is, 'newtons'.
At least by the time my generation was going through school, we learned both the English and metric systems. Most people who know how to use any reasonable amount of math could work with either system. If the US switched over to the metric system, most people would probably need a fairly short adjustment period just to get a general feeling of, for example, how many grams of lunch meat to order to make their sandwiches for the week, or learn to gauge how hot or cold it is outside when temperature is reported in celsius. There's no really good reason to stick with a system of measures that's so much more complicated.
A lbf is force and a slug is mass.
A slug is a rarely used non-imperial unit of mass invented in the early 1900s. The US aerospace community does use the slug, but only for moments and products of inertia. For mass, the aerospace community uses the avoirdupois pound, abbreviation lb, or lbm to be pedantically clear on the distinction between pounds-force and pounds (mass). The poundal? I don't know anyone who uses poundals.Unless you're talking about a lbm which is the mass and a poundal is the force.
Back to the main topic of this thread. A lot of the software for these new vehicles, including the flight software, is in metric because as far as software is concerned, converting to metric is a simple matter of multiplying by the appropriate conversion factor.Anyway $370 million to convert units? What the hell are they doing there? I would assume everything now is in digitized format, so conversion would be as simple (or simpler) than pushing a button.
I suspect you might be misreading NASA's decision. NASA is not saying they will use the imperial system only. That would require a lot of rework on a lot of things that are already in SI units. NASA is just saying that specs, processes, parts, machining, etc. that currently are imperial-based can stay that way.I suspect that this might be some of the politics behind the Nasa decision, spending $300M to allow foreign suppliers to bid on projects might not suit everyone.
