Kilograms
That depends a lot on what you want to measure: the cow's length, width, volume, mass, density, color, ...
A cow's mass is measured in kilograms. Her weight is also in kilograms, as well as in pounds.
That depends on what you mean by "measure": are you asking about measuring weight, or height/length? Weight is measured in pounds (lbs) or kilograms (kg). Height/length is measured in inches, centimeters, meters or feet
Kilograms - An adult cow weighs between 300 and 350kg.
A kilogram.
Put her on a truck and have the truck weighed on a balance scale (NOT a spring scale). From this you can get true mass.
Cows are measured in kilograms or pounds. A scale or weight tape is used to get a weight of a bovine animal.
The mass of an average adult cow typically ranges from 450 to 1,000 kilograms, depending on the breed and its purpose (dairy or beef). Dairy breeds like Holsteins may weigh around 680 to 900 kg, while beef breeds such as Angus can be heavier, often exceeding 1,000 kg.
That is immaterial, since it really cannot be measured.
you use pounds or, since you're asking about metric measure, kilograms. You could use either but the answer in kilograms is much easier to read and write since. For example, if the cow weighs 700 lbs, its weight in grams would be 317,514 g. It's weight in kilograms would be 317.5 kg.
By Cow/calf units.
To estimate the weight of a cow, one common method is to use a weight tape, which is a flexible measuring tape designed to measure the girth of the cow. You measure the circumference of the cow's girth, typically just behind the front legs, and then refer to a weight tape chart to find the approximate weight. Alternatively, you can use the formula: Weight (lbs) = (Girth in inches² x Length in inches) / 300, where length is measured from the point of the shoulder to the pin bone. These methods provide a good estimate, though actual weights may vary.
