Blood is red. But finding out if this is âtrueâ is like squeezing blood from a stone. Having said all that, please do note that here we are speaking only of mammalian blood. Other blood is red, and other things that we may equate to blood is a different color, but often, the term âblooodâ is not applied.
There are 128 fluid ounces in a U.S. gallon. In the United States, the gallon is a standard liquid measurement. One gallon contains 4 quarts, which is also equivalent to 8 pints or 16 cups of liquid.Other countries use liters over gallons when it comes to liquid measurement.
The gallon was divided into four quarts, the quart into two pints, the pint into four gills, and the gill into five ounces. Thus, there were 160 imperial fluid ounces to the gallon making the mass of a fluid ounce of water approximately one avoirdupois ounce (28.4 g). This relationship is still approximately valid even though the imperial gallon's definition was later revised to be 4.54609 litres, making the imperial fluid ounce exactly 28.4130625 ml.
