Baseball - How far is the pitching mound from home plate?

I imagine it gets no more correct than this.

"The pitcher’s plate shall be a rectangular slab of whitened rubber, 24 inches by 6 inches. It shall be set in the ground as shown in Diagrams 1 and 2, so that the distance between the pitcher’s plate and home base (the rear point of home plate) shall be 60 feet, 6 inches."

60 feet and 6 inches.

The mound distance is not the same as the distance from pitcher's rubber to home plate, and as it depends on from what point on the mound you are measuring. Using the dimensions given from the rule book, it'd be approx. 57.5 feet from the center of the mound to home plate. Given that the mound is 18 feet in diameter, one can figure out other distances from various parts of the mound to home.

"Installed 'to prevent trickery,' Rule 1, Section 2 required that....." from Robboy's link.

Years ago my husband built and maintained pitcher's mounds, and I can tell you some teams liked to cheat on the dimensions and distances. I was never sure if an inch gave a physical advantage or if it was mainly psychological.
