4 things right off the bat. 1: No I can't just use an online converter, they all use javascript and won't work on my phone. 2: This is assuming the area being measured is a square with equal sides. 3: I don't want any crap about my scientific pickiness in fantasy, this has little to do with writing and is not in the research section for that reason, I just want some quick math help. 4: I graduated high school with a low D in 7th grade math, so this post may be amusing and/or confusing. So here goes nothing: I need to know how many square feet are in 49 square miles and I keep running into what seems to be an inconsistency. This children's dictionary from the 80s says 1 sq mi=640 acres, 1 acre=160 sq rods, 1 sq rod=10.25 sq yards, and 1 sq yd=9 sq ft. So first I tried 49*640=31,360 acres, 31,360*160=5,017,600 sq rods, 5,017,600*10.25=51,430,400 sq yds, then 51,430,400*9=462,873,600 sq ft. That's just one possible answer I got.
