Conversion question

[shwncplnd]

Would anyone happen to know how many degrees are in a meter, or a reference to work off of?

Degrees in meters?!? Did I miss something here?

Degrees of latitude / longitude?

Earth's equator is 40,000 km I think
So one degree of longitude at the equator is 111,111 metres
And one minute is 1,852 metres

An unusual request! It might help to know more about what you are using it for.

It depends on where you are and the reference system you are using. Here are a few links that may help (various levels of sophistication).

LAST EDITED ON Jul-27-02 AT 06:20PM (EDT)[p]I'm using it for FSSoundScape. You can activate sounds within a certain radius, and I'm not too up-to-date on how long a meter is. If I use coordinates to decide how far out I want the sound heard, I can find out how many degrees it is, but I wasn't sure about the meters part. Thanks for the linx. I'll be checking those out here shortly.

Hi,

The links I gave you may help, but most are for people needing much more accuracy than you probably will. Here is a calculator that may be close enough for your purposes: "for calculating location, bearing, distance, time enroute, winds aloft, headings and more".

The way FSSoundScape works, is you activate a sound to play for a given radius around wherever your plane is whenever you activate it. Say for example, you want to have hanger sounds active when you're near the hangers. In the sound options, you can select how many meters away from your reference point that the sound can be heard. Naturally, for hanger sounds, the distance won't be very far, but as for a heli fly by sound, you might want to set the radius covering the entire airport so that way you'll hear it anywhere @ the airport instead of just by the hangers or @ the gates. That's basically why I'm wondering about the conversions. Say I slew my plane to the center of the airport, write down my coordinates. Then, I'll slew to a distance so that the diameter includes the whole airport. I write down those coordinates. However many degrees I've gone, I would need to know how many meters that is. I hope that made sense. For those who get into goodies like FSSoundScape, I highly recommend it. Then again, I thoroughly enjoy every LAGO product I own. Between them and DF, it's hard to save any money. :)

Here is the motherload for aviation conversion and everything else under the sun starting with the aviation selection page. Scroll under the table for more groups of converters, good luck.
