I'll post my interesting measurement as a puzzle:
If you have a rope long enough to wrap around the equator of Mars, how much longer must the rope be to allow a 6 Foot tall man to walk underneath it all the way around?

MY 'FAMOUS' CC3 MAPS: Thunderspire; Pyramid of Shadows; King of the Trollhaunt Warrens; Demon Queen's Enclave
r = radius of Mars in feet
C1 = circumference of Mars in feet
C2 = new length of rope in feet
pi = 3.14159
L = additional length of rope necessary.
C1 = 2 * pi * r
C2 = 2 * pi * ( r + 6 )
C2 - C1 = L
Equatorial radius of Mars = 3396.2 km = 11142388 feet
C1 = 70009629 feet
C2 = 70009667 feet
L = 38 feet.
That doesn't seem long enough. Maybe I'll recheck my math...
edit: No, I'm right. C + x = ( 2 * pi * r ) + ( 2 * pi * ( r + x ) ) That's kind of strange; you'd think it would be much bigger.

Nope, you got it, it's not that long is it? People think it needs to be really long, like miles, but only a mere 38 feet.
Infact it doesn;t matter what the Circumference is. Mercury, Pluto, Jupiter, etc, it always will be 38 feet

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:

It would be smaller if the man could limbo dance his way around Mars.
The U.S. officially adopted the metric system somewhere around the 1930's, I think. But like many populaces, we use both in everyday practice. We buy Pepsi in 2-liter bottles but milk & gasoline in gallons. We measure the "grams of fat" and "mg of sodium" in a Quarter-Pounder (a McDonalds hamburger). We give a pint of blood but receive cc's of plasma. Our wrenches come in both "mm" and "in". Our speedometers show both kph and mph. Cocaine is sold on the street by the "kee" (kilo[gram]), but pot by the ounce or pound.I really wish the world (read that as the US) would just stop fooling around and adopt the metric system
...I completely agree. Seems the US finds learning from the rest of the world a sign of weakness or failure.
btw ... the day I can't buy a pint in a pub in Britain will be a day I shed a tear.
