This system is nearly 300 years old and past due for
an overhaul. Get with the program you people. I'm
really sick of trying to explain to my students stupid
measurements like F, lb., mile, oz.
NOBODY USES THESE ANYMORE!
Pehaps if we clone Henry VIII he will be happy, but that
is about it!
Now if you will excuse me I have drunk nearly a hogshead
of ale tonight and I have to walk two chains to my domicile. |

Number of hits on Google Groups for July 1990, 1995, 2000, and January 2002. Nothing after that because Moore started making his film and hits with the word Fahrenheit suddenly rose threefold.
Fahrenheit - 259, 8780, 31500, 46000
Celsius - 185, 6280, 30100, 47600
So you can see celsius has surpassed fahrenheit. Probably just a matter of time (long time). Loooong time. |

Only a quarter billion English speakers use it.
So keep explaining it to your students. It ain't going anywhere soon.
I was raised on metric in Canada but due to our proximity to America I've picked up the conversions over time and it's pretty straight forward now.
Adapt your materials. I do. And if it's in their course books, it's a fun exercise to put the conversion rate on the board and then say: "Okay, 55 miles equals how many kilometres" and watch them furiously do the math. They love that. |

Wow...it was 101 FAHRENHEIT back home today! Maybe it's because we like big numbers (101F degrees, 200lbs) |

The imperial system is good for such things as crashing space probes worth hundreds of millions of dollars:
Quote: |
The Mars Climate Orbiter was destroyed when a navigation error caused the spacecraft to miss its intended 140 - 150 km altitude above Mars during orbit insertion, instead entering the Martian atmosphere at about 57 km. The spacecraft would have been destroyed by atmospheric stresses and friction at this low altitude. A review board found that some data was calculated on the ground in Imperial units (pounds) and reported that way to the navigation team, who were expecting the data in metric units (newtons).
...the Mars Climate Orbiter��s reaction wheels were kept within their linear (unsaturated) range through thruster firings in a procedure called Angular Momentum Desaturation (AMD). When an AMD event occurred, relevant spacecraft data was telemetered to the ground, processed, and placed into a file called the AMD file. The JPL operations navigation team used data derived from the AMD file to model the forces on the spacecraft resulting from these specific thruster firings. Modeling of these small forces is critical for accurately determining the spacecraft��s trajectory. Immediately after the thruster firing, the velocity change (DeltaV) is computed using the firing time for each of the thrusters, and an impulse bit, which models each thruster's performance. The calculation of the thruster performance is carried out both on-board the spacecraft and on ground support computers. The AMD software installed on the spacecraft used metric units, newton seconds (N��s), for the impulse and was correct. The ground software reported the impulse bit to the AMD file in imperial units of pounds (force) seconds (lbf��s), rather than the metric units required by the project's Software Interface Specification. Subsequent processing of the impulse bit values from the AMD file by the navigation software underestimated the effect of the thruster firings on the spacecraft trajectory by a factor of 4.45 (1 pound force = 4.45 newtons). |

I kind of agree with the OP on this one. I think the world should agree on something. Metric would be a good place to start.
When I was a kid it was gallons, miles, feet, inches, Celsius, pounds, ounces (for food and dope ), grams (for dope ), and it all got a bit hazy later on.
Maybe it was all that dope
Now it's feet/inches for height but cm are fine. It's pounds for weight but I can live with kg. Miles are still commonly used, but km, not a problem.
I can't remember gallons too well, but we used to have buckets of 1 or 2 or 5 or 10 gallon units. I think liters have kicked their asses to the curb.
It's always been Celsius for me though. Fahrenheit still confuses me.
Others, likes "stones" for weight, are totally foreign to me.
Since America uses a lot of this, I can live with Shaq being 7 foot 2 and Miami being 50 or whatever miles from Havana. And the average "cat" or dude weighing 200 pounds!
Or is that 225 cm, 85 km and 91 kg?
I forget.

Didn't the road signs in Canada use both km and miles, and the speedometers too? I recall scales of weight and height showing both systems as well.
What a confusing lot we all are!
And how many hectares are there in a lot anyway? |

I don't care what system...let's just all pick one! I flunked 4th grade math and can't handle the conversion charts. |

I learned the other day that temperatures in saunas can exceed boiling. They can get as high as 120 C.
There are these sauna competitions in Germany and of course Finland where these guys will sit in a room that is, quite literally, above boiling temp. If you have a glass of water next to you, it'll start bubbling and evaporating. Needless to say, they keep the humidity way down so you won't get scalded.
Some guys can last in there up to 15 minutes. 15 minutes!! Women have a harder time with it, they can take about 8.
Google "sauna competition."
It blew me away because I'd always thought that boiling temp would kill a man. And it would if you stayed in there too long. But I had no idea that humans could even survive above-boiling temperatures.
The object of the comeptition is to be the last to leave on your own, unassisted.
Anyway, speaking of heat. Did you know that? |

The first time I left Canada was in 1998 when I went to Estonia and they have saunas in each house too, like the Finns. You can't wear a towel in the sauna because it gets so hot it feels like you're wearing a piece of burning steel on your lap. It hurt to breathe. Then in between we would go and sit outside in the buff and eat apples, even though it was nearing November and the temperature was always around zero.
Back to the op, standardization is a definate must. Using one system is as necessary as using one language for scientific documents. We cripple ourselves as people when we do otherwise. |

The U.S. Military uses Metric but since they can force it they can. Awhile back the government (u.s.a) decided everyone is going metric.
It was quite comical. (I am an American BTW). The thing was they put up all the road signs and such and changed some commercial products but basically the American public said "no thank you very much". I don't know why. You can buy a liter of Cola but it is just a word. It looks a quart to me.
Americans in their own special way just SAID NO! Government had/has bigger fish to fry and gave up. They teach both in school but Metric is largely ignored.
I am used to it but it drives me crazy...30 degrees to me is freaking cold. But I like my weight alot BETTER in kgs. Aw if only I could pick and choose. Since I didn't buy drugs I didn't have to worry about it so much.
I find it interesting that Canadians switched so easily and Americans just simply refused. Seriously refused. If the government tried to force it again I am sure it would be ignored again and militantly so. It is such a quirk. Has nothing to do with intelligence just a strange cultural quirk.
Ah...sometimes I do love my compatriots in the U.S.A.

American scientists do use metric and celsius. |
