one inch on the map equals about how many miles on earth?
372127
It would depend on the map.  There should be a 'scale' on it someplace (usually in a corner) that will tell you.

Earth ranges from 7,926 miles to 7900 miles, depending on your location.\n\nThis is approximately 12,756km
393529
567.95 miles\ni looked it up on map quest
78436
The diameter of the earth at the equator is 7,926.41 miles
814781
Elementary conversion: \nTo covert miles into kilometers just use the fact\n1.00000 Mile = 1.60934 Kilometers

A nautical mile is 1,852 meters, or 1.852 kilometers. In the English measurement system, a nautical mile is 1.1508 miles, or 6,076 feet.

In the field of mapping or drafting, it's how large or small the drawing is.  For instance, one inch = one hundred feet or one inch =  fifty miles.

Well as far as a formula i can't help you there. i just happen to own a program that allows me to draw perfect shapes of any size and diminsion them accordingly (auto CADD). and at the top of your 300 ft house, or where ever it is that your measuring from the horizon at sea level is a tad over 21 miles away (21.20389 to be analy exact). first you must know the the earths circumfrance (i know i can't spell) which is 20,890,637 ft, next you have to know the distance you are away from the earth (which you do, 300 ft). now you have to know the formula for finding a line that intersects your hieght and crosses tangentally across the earths surface. know you have your triangle and apply the Pythagorean theorem. you have an answer.

G'day Dragon Warrior,\n\nThank you for your question.\n\nThe diameter of the earth in miles is 7,296 miles at the equator and 7,900 at the poles.\n\nI have attached sources for your reference.\n\nRegards

On the map I'm looking at, about 1/4 of an inch.

Circumference is 25,000 miles.  the diameter is about 7,950 miles, just under 8,000 miles (the earth isn't quite a sphere, it is a little pudgy at the equator, so the diameter varies slightly for our "oblique spheroid" which isn't a perfect sphere).

Miles?  I think it is more like inches.
715942
the radius of the Earth 6375.654784689 Km. There are many living things on it and it will not be ever counted exactly.

Approx 12,451 miles.  See below (Divide the circumference by 2 since you are only going half way around the world)

My best advice is to get the smallest scale map of the area you can find, and use the distance legend to estimate it (you know, like one inch equals 3 miles in the map legend.). Maybe even on Yahoo maps if accuracy isn't that important-best would be a paper map. I can't find the info on the net either.

1 miles is equal to approxamitely 1.609344 km and 1 km is about 0.6213711922 mile

At the equator, the earth is approx 24,000 in circumference.  So, how fast can you walk? That's how long it will take.  HINT:  Go to the North or South pole and walk around in a little circle, then you've gone "around" all the longitudes of the whole world in a few steps.
