A circle has 360 degrees in total. Therefore, a 1-degree angle represents 1/360th of the circle. This can be simplified to 1/360. So, a 1-degree angle is 1/360th of a circle.
An arc second is a measurement of an angle, so you would need to know how far away the object is. From there, there are two ways to proceed: 1. Use a circle with the distance as the radius a. find the degree fraction (degrees/360; there are 3600 arcseconds in 1 degree) b. find the circumference of the circle and multiply by the degree fraction 2. Set up a triangle and use a trigonometric function.
an infinite fraction of a degree less than 90 or 90 minus 1/infinity

each degree is 60 minutes, and each minute is 60 seconds. 1/3600.
