# How do you convert arcminutes into distance?

An arcminute is a portion o a degree in a circle ($\frac{1}{60}$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 ($2 \cdot \pi \cdot r$) and divide it by 21600 ($360 \cdot 60$).
