Those two are utterly unrelated; you can't convert one to the other.
Approx 111 km
Earth's equatorial radius is 6,378 km, so its circumference is 40,074 km (2 x pi x 6378). Dividing its circumference by 360 yields 111.32 km per degree.
1 degree of latitude =70 miles (112 km)
1 degree of latitude is about 111 km or about 69 miles. Anywhere.
600.98 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.
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.

111.1111 km (69.0412 miles) The circumference of the Earth is 40 000 km at the great circle passing through Paris - old definition from the Metric System. So 1 degree of latitude (N-S) would be 40 000 / 360 = 111.1111. For 1 degree of longitude (E-W) would depend on how far North or South you are. At the equator 111.1111 km, at the poles 0 km.
