What is 1 degree of longitude?

Answer 1

One degree of longitude is approximately 69 miles (111 km) apart at the equator; since they converge at the North and South Poles, the distance gets smaller as they near the poles.

Answer 2

One degree of latitude is approximately 69 miles (111 km) apart. However, since the Earth is a oblate ellipsoid (slightly egg-shaped), the distance between a degree of longitude varies by a small range.

Answer 3

That depends on the scale of the map you use. On a small scale map (Remember, small scale = big area) longitude lines may be 10 or 15 degrees apart, while on a large scale map, they are probably one degree apart or even 15 minutes (one quarter degree) apart. We can measure them as finely as you want to.

Answer 4

All longitudes converge (meet / come together) at the north and south poles,

so the distance between any two of them depends on how far you are from

the equator (your latitude).

Along the equator, 1 degree of longitude spans about 69.1 miles (111 km).

At 45 degrees latitude (roughly Bordeaux, Grenoble, Cremona, Belgrade,

Salem OR, Minneapolis, Wausau WI, Alpena MI, Bangor ME, Halifax NS,

Dunedin NZ), it's about 48.8 miles (78.5 km).

At the north or south poles, no amount of longitude covers any distance at all.

Answer 5

It changes at different places on Earth. The farther you are from the equator,

the shorter a degree of longitude is. Right on the equator, it's about 69.1 miles,

and at either the north or south pole, it's zero.

In general, the length of one degree of longitude is

(69.1 miles) times (the cosine of your latitude).

Answer 6

That depends how far north or south you are.

The lines of constant longitude all meet at the poles. So the farther you are from the equator, the closer together the degrees of longitude are.

On the equator, 1 degree of longitude is about 69 miles. At the north or south pole, the point where the pole comes up out of the ground lies on every longitude, so the distance between them is zero. In between the equator and the pole, the length of one degree of longitude is something between zero and 69 miles.

Answer 7

The distance between any two lines of longitude varies with the latitude. One decimal degree of longitude at the equator is approximately 111 km (69 miles). A degree of longitude at 45 degrees latitude is ~79km (49 miles) and ~2k (1.2 miles) at 89 degrees latitude. The distance between bands of longitude gets narrower as you get closer to the poles and at the North or South pole all points of longitude converge so the distance at that point is zero.

Answer 8

It's 69.1 miles on the equator, and zero at either pole, since the longitudes all merge at the poles.

Answer 9

For 1 degree of latitude, figure on 68.94 miles / 110.95 kilometers.

Answer 10

1 degree of latitude represents a distance of about 69.1 miles along the surface.
