The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
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 hundredweight has had many values. In England in around 1300, different hundreds (centum in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 pounds (50.80 kg). The United States and Canada came to use the term "hundredweight" to refer to a unit of 100 pounds (45.
Small fruits and vegetables are often sold in dry pints and dry quarts. The US dry gallon is less commonly used, and is not included in the handbook that many states recognize as the authority on measurement law. [23] [24] However pecks, or bushels are sometimes used—particularly for grapes, apples and similar fruits in agricultural regions.
In some places potatoes might be sold by the firkin—usually a liquid measure—with one town defining a firkin as 3 bushels, and the next town as 2 1/2 bushels. [22] The pint was the smallest unit in the corn measure. The corn gallon, one eighth of a bushel, was approximately 268.8 cubic inches.
The definition of units of weight above a pound differed between the customary and the imperial system - the imperial system employed the stone of 14 pounds, the hundredweight of 8 stone [Note 6] and the ton of 2240 pounds (20 hundredweight), while the customary system of units did not employ the stone but has a hundredweight of 100 pounds and ...
The multiple levels and slots of the large machine align the days-old birds in single files. Each chick is then shuttled on a blue conveyor belt past high-speed cameras that analyze their feathers ...
Such scales are used to make the most accurate of fine measurements, such as in the needs of empirical chemistry. Avoirdupois ( / ˌ æ v ər d ə ˈ p ɔɪ z , ˌ æ v w ɑːr dj uː ˈ p w ɑː / ; [ 1 ] abbreviated avdp. ) [ 2 ] is a measurement system of weights that uses pounds and ounces as units.
