About these units

US Fluid Ounce (fl oz)

US customaryCurrent unit

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).

Gō (gō)

JapaneseTraditional unit (still used in some regions)

A tenth of a shō, about 180.39 mL. Rice is still sold and cooked by the gō.

Gō is the smallest of the everyday Japanese dry and liquid measures, one tenth of a shō. Its exact size under the 1891 law is 2401/13,310 L, about 180.4 mL, matching the figure used here.

Rice is the unit's natural home. A gō is regarded as an appropriate serving of rice or sake, and electric rice cookers sold in Japan come with a measuring cup of exactly this size, so recipes still call for rice by the gō.

Since the 1959 Measurement Act the gō has had no legal standing in trade, but the cup survives in kitchens. Compared with a US cup of about 237 mL, it is a noticeably smaller measure, which is worth remembering when converting rice recipes.

1 gō = 0.1803906837 liters (approximately).
