A wheel or the blades of a fan.
In general, you can't convert between hours and degrees. However, if you have an object that rotates at a specified rate, you can say that the object rotates at so-and-so many degrees per hour, per second, etc. For example, Earth rotates at about 15 degrees/hour.

AXIS is the straight line about which a body or geometric object rotates or may be conceived to rotate..
A rotation is a movement of an object in a circular motion. A two-dimensional object rotates around a center (or point) of rotation. A three-dimensional object rotates around a line called an axis.
An imaginary line around which an object rotates.
Jupiter has the fastest rotational rate - it varies with latitude - but at the equator it rotates at about 45,300 km/h.
A degree is a measure of angular separation while an hour is a measure of time. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without further information. If you have an object that rotates at a specified rate, you can say that the object rotates at so-and-so many degrees per hour, per second, etc. For example, Earth rotates at about 15 degrees/hour.
The moon.
It's orbit.
That would be the axis.
Any object that rotates has a tendency to continue rotating.
Because of the movement of the stars and other observable stellar object's.
