How do you convert arc second into meter?

Answer:

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.
