Stone Calculation...

[Mike Westerling]

I measured my stone that was supposed to be 325 (but was never actually weighed) it was a hair over 63" around. I swear it's gotta be heavier because I can load a 320 5 times and this one's killing me! I can't take it anymore....Could some one please be kind enough to calculate and tell me what that should weigh based on the measurement?
Thanks in advance!

Just load it into the back of a truck, and go weigh it on a truck scale. Then, take the stone out, and weigh the truck again. That's how I weighed my concrete filled keg, and it was 320 on the dot.

I think you should also weigh that "320" because there's no freakin' way you'er that much better than me at stones!!! :EP:

go to ontariostrongman.ca(or something like that). They have a great stone calculator on the website.

I went to the ontariostrongman site and according to their calculator my stone should be 348!

Paul,
I will eventually go and weigh it but now I feel a bit better about my performance today.

63" circum. = 10" radius (.833')
Volume = (4/3) * pi * r^3 = (4/3) * 3.1415 * .833^3 = 2.423 cubic ft.
Concrete is between 140-150 lb/ft^3, so your stone should be between 339-363 lbs.

Thanks.
