Degrees are used to measure angles, as well as arc lengths (meaning the distance around part of a circle). So the number of degrees per inch depends on the size of the circle, or sphere.
For instance, if I draw a circle with a radius of 1 inch, then 360 degrees (all the way around the circle) corresponds to 2π inches, about 6.283 inches. So each degree is about 0.0175 inches.
But if the circle has a radius of 1 mile, then 360 degrees makes about 6.283 miles, so each degree is about 0.0175 miles, which is over 92 feet!
My point, and I do have one, is that in order to find the proportion of inches (or mm) to degrees, you have to know the size of the curved object in question. Hope that helps!

There are two forms of degrees. The first is temperature, and the second is direction. The Fahrenheit scale was first determined by the temperature difference of water as it fell off a waterfall. So for that waterfall (I don’t remember which one) on that day there was a direct relationship between the temperature and the distance.
The degree measurement that you are probably thinking about is the angle. A triangle is described by its angles and the lengths of its sides, however several triangles can have the same angles. It all depends on their length. The angle can be the same, but the distance can vary, so you can’t measure it in inches, or with any other linear measurement.
Degrees can be used in several ways. If a soldier is trying to order a missile strike on a specific building, but he doesn’t know how far away he is from it, then he can use a compass and measure the angle difference to find the target. The soldier knows where he is at, on a map. He is either at a known location or he can uses his GPS to give him the exact spot. But the GPS can’t tell him where the building is unless he actually goes there. He can find a known location, say a hilltop or a water tower. He radios in his location, identifies the known location and reads the angle to if from his compass (the hill or water tower), and then angle to the spot he wants hit. All the US military use the same maps so other soldiers can find that map and know exactly where to make the attack. The soldier doesn’t know the distance between himself and the known point or the target he wants to hit, but based on his known point on the map he doesn’t need to. He can still call the strike in though. This is exactly how the marines called in an artillery strike during WWII (before there was laser measurement) or the way that Special Forces units call in one today (so no one can back track the laser to find the Special Forces unit position).
An angle is measured in degrees, while distance is measured in feet (or whatever linear unit you use). They are measured in two different methods. Comparing degrees and inches is like trying to compare inches and minutes. A car moving at 20 miles per hour can travel a distance of 5, 10, 15 or 20 miles depending on the time spent traveling (15 minutes, 30 minutes, 45 minutes, or 60 minutes). To know how far the car has traveled you need two different pieces of information the time and the speed. If you know this then you can tell how far the car has gone from a known location. If we want to know where the car is you need to know the direction it went. The only way to determine that from the starting point is if you know the angle, which is measured in degrees.

I think that the question and the meaning are confused here. What should be the question relates to the grade, or slope of a straight line. For instance if you wanted to grade a landscape 1/2 degree per foot, it would be about .188 inch in 12 inches with a linear increase by distance. Or approximately 18.8 inches in 100 feet. That s how I would describe the impossible answer to the wrong question.

Your question illustrates a basic misconception about length and angle measurement. It is not unlike trying to compare two entirely different things in terms of each other, ie apples and oranges. You can speak about a degree of separation between two things as a distance but in order to do so you must state or know how far away those two things are. Example the moon is approximately 250 thousand miles from earth (its distance varies as the orbit of the moon like many other natural satellites in the solar system is not perfectly circular) to the observer on earth the angular width or diameter of the moon isapproximately the same as a penny held at arms length. This angle is about 1/2 degree.

That's kinda like asking, "How many inches is a pound."
An inch (or mm) is a unit of linear distance. A degree is a measure of rotation.

about 25 mm
1 inch = 2.54 cm
1 cm = 10 mm
so 1 inch = 25.4 mm

degree is the measure of an angle.
"in" or "mm" are measures of distance.
You're asking us how many cats are in a dog...
But if you really want an answer: 42.
