A Shit-ton is equivalent to 24 metric assloads, or 1/10th of a fuck-ton.
Used to measure un-quantifiable amounts of something. Although it can be used in the measurement of very large people it actually is not a unit of weight.
Widely adaptable large unit of measure. Generally speaking, take an amount of something that an average person may have and add a shitload more to it. This results in a shit-ton.
Shit-ton, despite sounding like a measure of mass, is actually a measure of volume. In other words - a shit-ton is the volume occupied by a ton (mass) of shit.
(On a tour of a brewery) "On our left, we have our primary fermenters. Each fermenter has the capacity of 2.3 shit-tons, which is equivalent to the amount of beer drunk every second in the United States"
Defined literally as 20 hundredshits, where one hundredshit equals 112 shits in the Imperial System (long or gross hundredshit) and 100 shits in the U.S. System (short or net hundredshit). Furthermore, a shit-ton-force refers to 2,000 shit forces, which is a hell of a lot (i.e. a shit-ton) of Newtons.
