Isn't it the length of a parabola with an amplitude of 6' that you are actually measuring? I seem to remember this question in my high school trig class.

Nope, it's circumference.Originally Posted by RPMiller
Observe in the following diagram where we start with a Circle of only radius 6. Each time we increase the radius by 6 feet, the circumference only oncreases by about 37.7 feet.

I see. I was thinking of it in slightly different terms. The rope and the man stay taut against the planet. Something like this:

On the topic of metric, I found this site providing a metric time-line:

One I use all the time when calculating scales:
1 degree of latitude = 69 miles (approx.) = 111 km (approx.)
Also, re: the metric system. Use the metric system all you want; I'll be sad the day the imperial system dies. Like your crazy uncle, it may not work as well but it sure has character. I like to design measurement systems for my conworld that have just as many irregularities and eccentricities.

Heres one that doesn't pop up much... a rood.

B.T.W I use google now to do a lot of measurement math. I guess most of you know but you can "search" for items like "3 miles in meters" and it generates the answers.
Hah, but it doesn't do roods !!!
It would be smaller if the man could limbo dance his way around Mars.
