How much is one degree in an inch?

One degree corresponds to approximately 0.0175 inches when measured along the circumference of a circle with a radius of one inch. This relationship is derived from the formula for arc length, where the arc length (in inches) equals the radius multiplied by the angle in radians. Since there are 360 degrees in a circle, one degree equals ( \frac{\pi}{180} ) radians, leading to the conversion. Thus, for practical purposes, one degree represents a very small distance along a circle's edge.
