I hate imperial units

Dec 12, 2006 73 Replies

There's a GNU 'units' program that can do all kinds of units conversions very easily. Just type the expression of what you have, and another expression of what you want, and it provides the scaling factor.

For example, translating the speed of light into furlongs/fortnight is just a matter of:

% units

2438 units, 71 prefixes, 32 nonlinear units

You have: 1 c You want: furlongs/fortnight * 1.8026175e+12 / 5.5474886e-13

Me three, but help is on the way. My favorite 'units' program (comes with Linux, and you can get a Windows version from e.g. Marv Klotz's site

You have: 200 btu*in/(ft^2*hr*degF) You want: W/m K * 28.845578 / 0.034667359

Interestingly, Google has a built-in calculator with units conversion (try searching for '160 pounds * 4000 feet in Calories') but I couldn't get it to parse the above.

Exposure to metric units happens in science classes. Exposure to imperial units happens outside of science class (with the exception of a few "units conversion examples" given near the beginning of the term).

Sure do. "There's no substitute for a well-oiled caboose!" LOL.

Our house is a designer house, Jetson's style from the early 70's. These were the days when they deliberatly made rooms non-square. Hallways turning off 55 degrees, meaning 27.5 degree cuts and the portions have to line up there. But they also have to line up at the other end where it also turns .... IOW a tile setter's nightmare.

The good thing is a 2" concrete bed over the raised foundation floor. Very solid and you don't really have to worry where the beams are. That must have been an expensive feature.

Exactly. One minute dry time and then you can still see the outer borders of that Sharpie line by the end of the cut.

I am going to have to do two more bathrooms. Some day. Not looking forward to it.

At the university I hung out mostly with MEs. They were less "nerdy" and they could pack in quite a few brewskys. They didn't understand us EE guys but that didn't matter. I raised the stock for EEs big time when the stereo went during a party. Other than lots of beer all they had was a few inbus wrenches. So I heated one up on the stove, grabbed it with pliers and mended a broken solder joint. All while heavily under the influence of Guinness.

How many bathrooms do you *have*? If it's much more than two, maybe you really should consider subbing it out...?

All a civil engineer has to do is be polite. ;-)

Then again...

If you have a jamb saw. I didn't and the molding was glued in place. Arrgh!

Wow! That's more powerful than our wood stove. The propane furnace has

125k but with today's inflationary propane prices that can slurp up money faster than anything. So we don't use it much.

Except for the coldest winter days we can run the wood stove at a lean

15k and it keeps it nice and cozy.

3-1/2. I never understood why a house needs this many but they were there when we bought it. Subbing out bath remodels gets really expensive. And you have to pay all that labor with after-tax money.

I got pretty good at laying tile. That certainly does not mean I enjoy it. It's hard on your back but a bathroom isn't such a large project. Unless the missus wants all the vanity cabinets re-tiled which was the case for one of them.

Mantel? ;-)

Many moons ago, I nailed an incredibly sweet contract, and I went nuts - I bought a 4-bedroom condo that had had a wall ripped out so it had

2 regular bedrooms and one double-sized, and two bathrooms, upstairs. Downstairs, there was a little half-bath right off the entryway. I was bragging about my new purchase, and I said, "I got three toilets!" Some guy said, "Now all you need is three assholes!"

I laughed. :-)

h!

Ouch! Mine is nailed in place. I simply pulled it all down,=20 filled the holes, stained and polyurethaned it, cut the bottoms to=20 size and put it all back up (pneumatic nailers are fantastic=20 things). I had to do the base molding anyway.

Our wood stove will drive us out of the house if it's above 0F, so=20 we only use it in Jan/Feb. On the coldest days the boiler, if run=20 without the wood stove, will run about a 50% duty cycle. I'd go=20 broke on propane here. I switched from oil to natural gas about=20 ten years ago.

The coldest days here are -20F (nights have gotten down to -40). =20 :-(

--=20 Keith

You'll have that (damn speel chequers and homophones).

I have 2-1/2 baths in a 3 bedroom house. Well, the town thinks it's only a two bedroom and it's going to cost me $4K to pay off the town.

I didn't.

Keith

We will never have natural gas out here so were are stuck with a quasi-monopoly situation. They can pretty much charge what they want :-(

Not much global warming, eh? We certainly don't have one here when I look at our wood consumption over the years.

As a general rule, to invoke Google's unit conversion, use spaces rather than "*" and try spelling out the units if the abbreviation doesn't work. For example, this works when put in Google's search box:

henrys gross slugs in stone grain barns per square faraday

Just a thought: Is it a modern EPA rated stove? If not maybe you could consider one. Ours is a Quadrafire 3100 insert without catalytic converter. We didn't want a converter because their insert modules wear and are expensive. Plus they can take longer to "catch" and I find that we can reach a smoke free burn faster with this secondary combustion stove.

We can throttle that stove down to around 10,000BTU/hr and still maintain blue/white flames and no smoke from the chimney. On almond it burns 4-5hrs and even after an overnight there is plenty of coals and some heat left to get it going again in the morning.
