This is something we should really consider.
Lets compare.
There are 12 inches in a foot. 3 feet in a yard. 1760 yards to a mile.
OR
There are 100 centimeters a meter. 1000 in a kilometer.
Now do the math, real quick in your head???
How many inches in a yard? How many inches in a mile? It's so hard....
or
How many cm in a meter, 100, how many in a meters in a km, 1000. So easy
Seriously people, 10x 10 is so much easier than a fraction of 12 or a multiple of 12 and 3.
Come on, how many people in our culture know that 3/8 inch is .375, and why would they? This is king george or king dufus dumb.
1cm (width of your finger) x 100 = 1 meter (a bit longer than a yard) x 1000 = 1 km (less than a mile, about .62)
IF YOU THROW 100 METERS, YOU THROW 328 FEET, IF YOU'RE OUTSIDE THE CIRCLE 10 METERS, IT'S A 32.8foot PUTT.
