About these units
Shō (shō)
Exactly 2401/1331 liters, about 1.8039 L. Sake bottles still come in 1.8 L 'isshō-bin' sizes.
The character for shō depicts a ladle holding grain, and the measure began as roughly the amount held in two cupped hands, about 200 mL. Over the centuries the unit grew to about ten times that, and by the Edo period the standard box (masu) was the one used in Kyoto.
In 1669 the shogunate abolished the older Edo masu and ordered the slightly larger new Kyoto masu to be used everywhere. Guilds in Edo and Kyoto policed its size for roughly three centuries. The 1891 Weights and Measures Act then fixed the shō at 2401/1331 L, about 1.804 L, derived from the 64,827 cubic bu of that box.
Japanese sake is still sold in 1.8 L bottles known as isshō-bin, or one-shō bottles. Trade use of the shō was banned in 1959. Note that in China the shō is defined as exactly one litre, so the same word names a different size there.
1 shō = 1.803906837 liters (approximately).

US Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
