It is hard to guess what a Onager weights. But we have the answer:
An adult Onager (Equus hemionus) on average weights 235.62 kg (519.46 lbs).
The Onager is from the family Equidae (genus: Equus). They can live for up to 38.75 years. When reaching adult age, they grow up to 2.25 meter (7′ 5″). Usually, Onagers have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The onager (; Equus hemionus), also known as hemione or Asiatic wild ass, is a species of the family Equidae (horse family) native to Asia. A member of the subgenus Asinus, the onager was described and given its binomial name by German zoologist Peter Simon Pallas in 1775. Five subspecies have been recognized, one of which is extinct.The Asiatic wild ass is larger than the African wild ass at about 290 kg (640 lb) and 2.1 m (6.9 ft) (head-body length). They are reddish-brown or yellowish-brown in color and have broad dorsal stripe on the middle of the back. Unlike most horses and donkeys, onagers have never been domesticated. They are among the fastest mammals, as they can run as fast as 64 km/h (40 mph) to 70 km/h (43 mph). The onager is closely related to the African wild ass, as they both shared the same ancestor. The kiang, formerly considered a subspecies of Equus hemionus, diverged from the Asiatic wild ass and has been acknowledged as a distinct species.The onager formerly had a wider range from southwest and central to northern Asian countries, such as Israel, Saudi Arabia, Iraq, Jordan, Syria, Afghanistan, Russia, and Siberia, the prehistoric European wild ass subspecies ranged through Europe until the Bronze age. During early 20th century, the species lost most of its ranges in the Middle East and Eastern Asia. Today, onagers live in deserts and other arid regions of Iran, Pakistan, India, and Mongolia, including in Central Asian hot and cold deserts of Kazakhstan, Uzbekistan, Turkmenistan, and China.Other than deserts, it lives in grasslands, plains, steppes, and savannahs. Like many other large grazing animals, the onager’s range has contracted greatly under the pressures of poaching and habitat loss. Previously listed as Endangered, onagers have been classified as Near Threatened by IUCN in 2015. Of the five subspecies, one is extinct, two are endangered, and two are near threatened (their status in China is not well known). Persian onagers are currently being reintroduced in the Middle East as replacements for the extinct Syrian wild ass in the Arabian Peninsula, Israel and Jordan.
