Determining feet from Lat/Long coords

[Dougmeister]

How many feet are in 0.001 minutes?

 

Looking at the FAQ

here, I see that Latitudes are constant at 6.074 feet.

 

At my longitude (77 or so), how can I tell how far each minute is in feet?

 

I found my first cache (with lots of help yesterday at N 40° 15.251 W 076° 55.703.

 

Advise is greatly appreciated. Thanks.

To correct for the latitude, multiply by the cosine of the latitude.

 

So at the equator, latitude = 0

COS(0) = 1

therefore the 6.074'/minute is the same.

 

Near your location, lat is about 40 deg.

COS(40) = 0.766

0.766 X 6.074 = 4.653'/minute

 

And the other extreme: at the pole:

Lat = 90

COS(90) = 0

Therefore there are 0 feet/minute at the pole. Makes sense, right?

Before you get befuddled forget trying to measure feet. They are those things that carry you to a Cache. Get a good Mapping program. Then teach your self how to use UTM's
