Weight is measured in ounces and pounds (avoirdupois) as in the U.S. Volume is measured in imperial gallons , quarts , pints , fluid ounces , fluid drachms , and minims . The imperial gallon was originally defined as 10 pounds (4.5359 kg) of water in 1824, and refined as exactly 4.54609 litres in 1985.
[5] In 1824, the British Parliament defined the imperial gallon as the volume of ten pounds of water at standard temperature. [2] 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.
The imperial gallon was defined as the volume of 10 pounds of distilled water weighed in air with brass weights with the barometer standing at 30 inches of mercury (100 kilopascals; 15 pounds per square inch) and at a temperature of 62 °F (16.7 °C), which was calculated as 277.274 in 3 (or 4.543 706 784 L to ten significant figures).
The table of imperial avoirdupois mass is the same as the United States table up to one pound, but above that point, the tables differ. The imperial system has a hundredweight, defined as eight stone of 14 lb each, or 112 lb (50.802 345 44 kg), whereas a US hundredweight is 100 lb (45.359 237 kg). In both systems, 20 hundredweights make a ton.
The saying, "a pint's a pound the world around", refers to 16 US fluid ounces of water weighing approximately (about 4% more than) one pound avoirdupois. An imperial pint of water weighs a pound and a quarter ( 20 oz ).
Water bottles for personal use can have their capacity measured in fluid ounces or liters. For ounces, the measurements are typically in multiples of 8, for example 32 fl oz and 40 fl oz, which correspond closely to common metric variants including 1 liter and 1.2 liters. Rainfall is usually measured based on the height from the ground in ...
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

The ounce (/ ˈ aʊ n s /) is any of several different units of mass, weight, or volume and is derived almost unchanged from the uncia, an Ancient Roman unit of measurement.. The avoirdupois ounce (exactly 28.349 523 125 g) is 1 ⁄ 16 avoirdupois pound; this is the United States customary and British imperial ounce.
