Question

How do you convert arcminutes into distance?

Answer 1

You don't. At least not without more information.

Explanation:

An arcminute is a portion o a degree in a circle (`1/60`th of 1 degree). You need at least the radius of that circle or some other measurement to get distance or an arc.

To calculate the arc compromised by one arcminute you would take the circumference of the circle (`2*pi*r`) and divide it by 21600 (`360*60`).
