A penny is 0.0598 inches (1.52 mm) in thickness. (0.75 is the diamiter).
Hear me out. Now we gotta convert it to miles to divide 250 by the number (there's 6.21371e-7 miles in one mm). first convert the mm to inches (by dividing the length value by 63360). We get 9.444842171717e-7 or 9.44484e-7 for a shorter form. Last step 250/9.444842171717e = 264694796.312.
Oh btw I'm not very sure on this answer correct me please if I'm wrong.
