High school quick arithmetic techniques...
25, call it .25 or one-quarter.
One half of 8 is four, one half of 4 is two.
Throw in the right decimal places is 2000 pounds. (Couldn't be 200 lb, couldn't be 20,000 lb, must be 2000 lb.)
Yep, just for a quickie rough estimate, 2000 pounds is pretty close to a ton. :D
(Actually, I did this when that post ( RKL's ) first showed up. Mainly because my calculator was a foot beyond my reach.)
