How much does a Polynesian rat weight?

It is hard to guess what a Polynesian rat weights. But we have the answer:

An adult Polynesian rat (Rattus exulans) on average weights 50 grams (0.11 lbs).

The Polynesian rat is from the family Muridae (genus: Rattus). It is usually born with about 2 grams (0 lbs). When reaching adult age, they grow up to 11.9 cm (0′ 5″). On average, Polynesian rats can have babies 3 times per year with a litter size of 3.

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 average adult weight of a Polynesian rat is 50 grams (0.11 lbs)

The Polynesian rat, Pacific rat or little rat (Rattus exulans), known to the Māori as kiore, is the third most widespread species of rat in the world behind the brown rat and black rat. The Polynesian rat originated in Southeast Asia, and like its relatives, has become widespread, migrating to most Polynesian islands, including New Zealand, the Marshall Islands, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution.
