Yep. I say that because I was very recently looking into the network latency for computers on the other side of the world. I ran the same theoretical calculation of circumference of the earth divided by the speed of light and measured ping times and they lined up quite well. Now, to be clear, OP definitely has one up on me because I didn't notice the 1337, but it stuck in my head that to one significant digit it's ~100 milliseconds to get around the world. Now four significant digits stick in my head. Thanks OP!
