For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha (25-acre) pasture field might be able to support 15 adult cattle or 25 horses or 100 sheep: in that scheme each of these would be regarded as being 15 LUs, or 1.5 LUs per hectare (about 0.6 LUs per acre).
This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal units. [4] Estimation based on metabolic body size.
Being a ratio the FCR is dimensionless, that is, it is not affected by the units of measurement used to determine the FCR. [ 3 ] FCR a function of the animal's genetics [ 4 ] and age, [ 5 ] the quality and ingredients of the feed, [ 5 ] and the conditions in which the animal is kept, [ 1 ] [ 6 ] and storage and use of the feed by the farmworkers.
Dry Sheep Equivalent (DSE) is a standard unit frequently used in Australia to compare the feed requirements of different classes of stock or to assess the carrying capacity and potential productivity of a given farm or area of grazing land.
An animal unit is the equivalent of 1,000 pounds of "live" animal weight. [1] A thousand animal units equates to 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than 55 pounds (25 kg), 10,000 pigs weighing under 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg laying hens or pullets.

Various formulas are used for calculating grazing fees on public lands. Some examples are: For federal rangelands of the United States, the grazing fee "equals the $1.23 base established by the 1966 Western Livestock Grazing Survey multiplied by the result of the Forage Value Index (a derived index of the relative change in the previous year's average monthly rate per head for pasturing cattle ...

Church bell ringers use the unit commonly, [6] although church bell manufacturers are increasingly moving over to the metric system [citation needed]. Older blacksmiths' anvils are often stamped with a three-digit number indicating their total weight in hundredweight, quarter-hundredweight (28 lb (13 kg), abbreviated qr), and pounds.
