View Full Version : Mileage conversion???

Since there are many users on here from all over the world using Imperial and Metric, would it be feasible to have some kind of a mileage conversion calculator?

Simple way (IMHO) would be a small window with a conversion calculator so people can quickly and easily convert a distance from one unit of measure to another.

Complex way would be written in the code so that the numerical value before the word(s) (mile, miles, MPH, MP/H, kilometers, kms, kilometer, km, KMH, KM/H...etc) would be automatically calculated to whichever unit of measure a user preferred to see.

Example: "A great 100 mile ride" would appear as "A great 161 km ride" or vice versa depending on the user's preference.

Food for thought.

I love the idea, I'll look into implementing it.

that is a good idea. sure beats my post-it note that says: 1 mile = ~1.61km.

good idea I will look into it also, especially as Im Head of Marketing for the National Weights and Measures Lab here in the UK. Haha. I remember it this way: 1 km is 5/8 of a mile.

I usually use my head, but not everyone can do math as easily. I just figured if it could be done automatically it would be cool. I know activebody.org allows users to have the preference.

Has anyone considered just switching to metric? Imagine it. We all switch our bike computers to metric. (Temperature can come later). It's going to be that way someday, so why not now? I'll start Jan 1, 2005. Anyone else?

Java,

Good on you to swim against the stream. I always love hearing interviews with US riders like Lance when he speaks in km's and a bit of French in there too. Sounds like a Canadian!

I like metric because it's simple 1000 meters = 1 kilometer.
Imperial...5820 feet = 1 mile = 1760 yards.

Metric is easier as 'pedal' said above. I'm already metric, and here in oz, everything is metric anyway, i am so used to watching american movies and shows that have all this imperial measurement and temperature i get so confused! :(

Every time i hear someone say 80 degrees, i think HOLY **it, then i remember there in faranheight (excuse spelling), which is only about what, 30 celcius or something.

It would be great to have a system so everybody puts a preference down for metric or imperail.

As far as I can tell, the only reason why we keep the Imperial system; to watch your reaction durring movies.

how about a foruming parser that converts all measurements to metric or imperial from peoples posts. Toggleable option in user profile?

Now THAT would be awesome.

Awhile back I told an American friend that most of the world uses metric, and drives on the left side of the road. Now THAT was a reaction! :eek: What's funnier is when Americans cross the border and see the speed limit '100' , and they are FLYYYYYYYIN'!!

Try google instead, and write for an example "1 lbs in kg" and then you got the answer 1 pounds = 0.45359237 kilograms. And you can try it out on many diffrent measures just formulate it like I did...

Google on:-)actually pounds measure force and grams measure mass. 1/32 slug accelerated at 32 ft per second per second (earth's gravity) is one pound. The metric measurement of force is the newton.

Im not so good at your stones, pounds, miles, oz et., Im 100% metric, but try it yourself with something you want to know and I think it will work. It is easier if you have a real example so you can verify it, maybee I forgott imperial or something...

McDonalds Quarterpounder is that a measurement for force also? Otherwise it wheights around 110 grams and that seems ok...

Steff,

I appreciate your input, but that's exactly what I'm trying to get away from. We don't need to google the conversion, it's 1 km = 1.61 miles.

Now when I tell you that I went for a ride average speed was 27 km/h overall distance was 60 km's, max speed was 63 km/h. It would take a few calculations which would either mean opening the calculator on your computer, doing the math in your head, or something else that's a pain in the butt. If it was written in the program to do that for you, wouldn't it be simpler? Computers are supposed to work for us, not the other way around. ;)

McDonalds Quarterpounder is that a measurement for force also? Otherwise it weighs around 110 grams and that seems ok...Weight is what an object with mass gets in a gravitational field, or other acceleration. That means an object with a mass of one kilogram will generate a force of roughly two pounds in the earth's gravitational field. If we were to try the same comparison in permanent orbit, the object would still have a mss of one kilogram, but have zero weight.

Hmm, I dont know but when I search on google on pounds the first 30 hits is conversion charts and calculators between kg and pounds (refered as lbs also). For an example http://www.healthyweightforum.org/eng/converter.asp and that feels like its designed for weight purposes and pounds (lbs) is widly used at this forum, but maybe you use something else to measure your weight in.

I also looked up another source, Encylopedia Britannica and they write like this about "pounds" and read the words in the end "equal to"....

"Unit of weight in the avoirdupois system, the traditional European system of weight (incorporated into the British Imperial system and the U.S. system of weights and measures), equal to 16 oz, 7,000 grains, or 0.4536 kg."

So your 2 pounds have a zero weight i zero gravity.

Lots of folks don't know the difference between mass and weight, so the conventional description interchanges the two. Any elementary physics text will make the distinction very early. F=M*A

I dont know if you agree with the pound vs kilogram connection or if you want to write about the diffrenses between the words mass and weight in general?

I am not a big fan of such conversions because they lead to mistakes when the difference becomes important. In fact, I would prefer a metric based system, called Systeme Internationale, or SI for short, which premitsuse of words like kilometer and decagram, but has a prefence for retaining the basic usints, and using scientific notation, in order to avoid order of magnitude errors.

Ok, are you refering to the scientist that calculated on the shuttle or what it was, and forgott to convert to the right measureunit?
But if we are in a bicycleforum and people want to know how much 75 kg is in their measure that they know for an example lbs, how should you explain it in a simple way?

Apparently part of the issue was recycling computer code, too.

I agree that for the person trying to figure out how much weight is generated by 75 kg, a simple, rough calculation will help. Multiplying by 2.2 is easy enough. (75 kg implies roughly 165 pounds)

End of disscussion then? :)
