1 mile = X meeters?

Miles to metres and GPL track length measurement

Michael Barlow asked for a mile-to-metre conversion for top-speed testing of GPL car classes. Martin Granberg explained that GPL stores a 2D track length that ignores elevation, and others suggested the Smogbank test track or building a custom oval with GPLEA. A pedantic argument followed over whether 1609.3 or 1609.344 metres was correct.

I'm doing some re-testing on the GPL classes.. I mentioned in another thread about a test track, The closest I can find that is what I want is the Daytona track. Unfortunately, about 2/3rds down the back strait the track starts to go uphill destroying any chance of getting a absolute fasted possible strait line speed. In F3, the brabham hits 143 at that point but then slows down to 142 near the turn, and of course down to 140 through the turn. Any case, I ran enough laps to get a basic idea of fuel mileage. The track is 4023 meters long I'm assuming being measured at the center of the track. How many miles is 4023 meters? also, exactly how long is one mile? (5,xxx feet?) like I said before, just some odd testing for some odd but interesting facts. -- Michael A. Barlow currently Acting as "Head of Marketing" FILSCA (www.filsca.com)

One in the trk file - this is what I call "2d-length", not taking elevation changes into account . Measured along centerline of track. One in the ini file - Anything the creator choose to put in there. One in the graph of GPLRA - this is what I call "3d-length", taking into account all elevation changes. Measured along centerline of track. (in earlier versions of GPLRA the length stated was the 2d length) Daytona is rather flat so the difference between "2d" and "3d" length probably isn't very big.

Anyway, who wants to only eat fish?

Hmm, mention fish and you'll always get a response from a Norwegian :-)
I took the GPL editor application and opened the track.dat file. in there is the track length in meters so I can only *assume* it's right. All though I didn't take a look at each track section length and add them up. Any case, I did some tests at Daytona with the FG cars and found the top speed and fuel mileage for each marquee. Now to find out the 0 to 100 and 100 to 0 differences. (yes, I have too much time on my hands atm ;-) -- Michael A.

That is the "2d" length. If you have (unlikely, but it illustrates the problem) a track section which is 10 meters long but with an angle of 45 degrees (=10 meters high), and then another 10 m section with -45 degrees GPLEditor would say those 2 sections are 20 meters long combined. But the length the wheels would have to travel to cover those two sections is ofcourse longer than 20 meters. Cheers, /Martin

Dirty disgusting fish that absorb every unknown chemical dumped into the ocean? not me thankyou.

A mile is 1608 meters. And why don't you use smogbank for testing. Two long straights, and to large radius, slightly banked corners, it should be ideal for your purpose. Don't have a link i'm afraid. Lars G. On Tue, 02 Oct 2001 23:28:06 GMT, "Michael Barlow" <[email hidden]> wrote:

hmm.. I didn't realize that. I just automatically assumed it was a regular road course. Hopefully someone will post a link. I'll do some searching, but just in case I don't find it..... btw: you are close.. one mile = 1609.3000 meters. Thanks to those who pointed me to the US/metric conversion sites :-) 1 mile = 1609.300 metre 1 mile = 1760 yards 1 mile = 1.6093 km -- Michael A.

Even more intriguing 1609.300 = 1609.344 ? :-) Nit picking, perhaps, but it's not the same is it ? :-) Beers and cheers (uncle) Goy "The Pits" http://www.theuspits.com/ * Spam is for losers who can't get business any other way * "Spamkiller" http://www.spamkiller.com

now if that's true, is it ok to say: 1649.300 = 1609.304 ? SCNR :) BTW: Michael, if you really need different, special test tracks, look into the GPLEA track creating tutorial. Within an afternoon you should be able to do an oval with any desired properties. (I can do a driveable oval from scratch in 10 minutes, maybe 15 if you want banking :) The really big part of track creation is the addition of details (Trees, signs, spectators, houses, flagposts, the naked girl, etc..), the AI, setups, cover, .. none of this is needed for your performance tests, so you really can be set within minutes!
