Approx 111 km
Those two are utterly unrelated; you can't convert one to the other.

Yes. All latitudes are approximately 111 km apart.
Mainland Asia ranges through about 77° of latitude and 195° of longitude, distances of about 8,560 km long by 9,600 km wide according to Chambers, or 8,700 km long by 9,700 km wide according to Pearson's.
The locus of all points of zero latitude ... sometimes also known as the "Equator" ... is the longest parallel of constant latitude. It's length is the equatorial circumference of the earth ... roughly 24,900 miles (40,073 km) .
about 111.1 km
1 degree of latitude is about 111 km or about 69 miles. Anywhere.
1 degree of latitude =70 miles (112 km)
600.98 km
one minute of latitude is approximately 1.15 miles (1.853 km). You can just divide that by 60 to get the distance for one second and multiply 60 to get 60 minutes.
111.12 km
One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). One degree of latitude, and of longitude on the equator only, is also equal to about 60 nautical miles.
Lines of longitude are not parallel. They all converge at both the North Pole and the South Pole. Therefore there is no numeric constant to this value. The maximum distance represented by one degree of longitude, measured along a line of latitude (that is, parallel to the Equator), would be approximately 40,076 km divided by 360, or 111.3 km (69.2 mi).
One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). One degree of latitude, and of longitude on the equator only, is also equal to about 60 nautical miles.
It depends on your latitude. At the equator (0 degrees) a degree of longitude covers just over 111 km, so 8 degrees would be about 890 km. At 45 degrees of latitude, a degree of longitude covers just under 79 km, so 8 degress would be about 555 km. Check out the calculator in the related link. Enter the degrees of latitude and it gives the length of a degree at that point.
At the equator, the circumference of the Earth is 40,075.16 km ( 24,901.55 miles). Divide that into 360 equal pieces to get the distance for each one degree of longitude. A degree of longitude at the equator is equal to 111.32 km.
1 degree of latitude represents the same distance everywhere . . . about 111 km. 1 degree of longitude represents a distance of (111 km) x (cosine of the latitude). That's about 111 km along the equator and dwindles to zero at the poles, because all of the longitudes converge (meet, come together) at the poles.
