Is there a site that will show me the distance from point a to point b using geogrphical cordinates from gps?

I need to find a site where I can put in my geographical cordinates (according to a gps unit) and the cordinates of another location and print it off to show that it is within a 100 mile radius from point a (my house) to point b. I already have the cordinates… Just need the site.
