Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
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.
The former Weights and Measures office in Seven Sisters, London (590 Seven Sisters Road). The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
Cooking weights and measures. Measuring spoons (metric) – 1 mL, 5 mL, 15 mL, 50 mL, 100 mL, 125 mL. Measuring spoons (customary units) In recipes, quantities of ingredients may be specified by mass (commonly called weight), by volume, or by count . For most of history, most cookbooks did not specify quantities precisely, instead talking of "a ...
Hundredweight. The hundredweight (abbreviation: cwt ), formerly also known as the centum weight or quintal, is a British imperial and United States customary unit of weight or mass. Its value differs between the United States customary and British imperial systems. The two values are distinguished in American English as the short and long ...
In science and engineering, the weight of an object, is the force acting on the object due to acceleration of gravity. [1] [2] [3] Some standard textbooks [4] define weight as a vector quantity, the gravitational force acting on the object. Others [5] [6] define weight as a scalar quantity, the magnitude of the gravitational force.
The units of cubic length (the cubic inch, cubic foot, cubic mile, etc.) are the same in the imperial and US customary systems, but they differ in their specific units of volume (the bushel, gallon, fluid ounce, etc.). The US customary system has one set of units for fluids and another set for dry goods. The imperial system has only one set ...
This gave rise to the US survey foot for instance. The avoirdupois units of mass and weight differ for units larger than a pound (lb). The imperial system uses a stone of 14 lb, a long hundredweight of 112 lb and a long ton of 2240 lb. The stone is not used in the US and the hundredweights and tons are short: 100 lb and 2000 lb respectively.
