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.
The catty is traditionally equivalent to around 1 + 1 ⁄ 3 pound avoirdupois, formalised as 604.78982 grams in Hong Kong, [1] 604.5 grams historically in Vietnam, [2] 604.79 grams in Malaysia [3] and 604.8 grams in Singapore. [4] In some countries, the weight has been rounded to 600 grams (Taiwan, [5] Japan, Korea [6] and Thailand).
See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.

In the apothecaries' system, which was widely used in the United States until the middle of the 20th century, [15] the dram is the mass of 1 ⁄ 96 pounds apothecaries (lb ap), or 1 ⁄ 8 ounces apothecaries (oz ap or ℥) [5]: C-7 (the pound apothecaries and ounce apothecaries are equal to the troy pound (lb t), and troy ounce (oz t ...
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).
2,240 pounds (1,016.0 kilograms; 1.0160 metric tons) exactly 12% more than the 2,000 pounds of the North American short ton, being 20 long hundredweight (112 lb) rather than 20 short hundredweight (100 lb) the weight of 35 cubic feet (0.991 m 3) [2] of salt water with a density of 64 pounds per cubic foot (1.03 g/cm 3) [1]
