About these units
Tierce (tierce)
42 US gallons (159 L), a third of a tun. The size of a standard oil barrel.
Tierce is French for a third, and the cask earned the name as a third of a wine pipe, holding 42 wine gallons. Wikipedia credits a definition under Richard III with fixing the wine tierce at that size, and by around 1700 it was a standard shipping container for many goods in the English colonies, not only wine.
Its best known afterlife is in the oil fields. Pennsylvania producers, who started after the Drake well of 1859, first used whatever barrels they could find, including 40 and 45 gallon ones. Around 1866 they settled on the wine tierce, two gallons larger than a standard whisky barrel, and the 42 gallon figure was formally standardised by 1872 and adopted by federal agencies in 1882.
In US gallons the tierce is about 159 litres (158.99 L as used here), and the imperial equivalent of 35 gallons is nearly identical at 159.1 litres. That coincidence is why the unit lives on in the oil barrel, still quoted in petroleum markets even though no one ships crude in wooden casks of that size.
1 tierce = 158.9872949 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).
