It is hard to guess what a Rock vole weights. But we have the answer:
An adult Rock vole (Microtus chrotorrhinus) on average weights 39 grams (0.09 lbs).
The Rock vole is from the family Muridae (genus: Microtus). When reaching adult age, they grow up to 10.7 cm (0′ 5″). On average, Rock voles can have babies 2 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 rock vole (Microtus chrotorrhinus) is a medium-sized vole found in eastern North America. It is also called the yellow-nosed vole.This species is similar in appearance to the larger Taiga vole. It has short ears and a long tail which is paler underneath. The fur is greyish-brown with grey underparts and a yellowish nose. Its length averages 15 cm (5.9 in) long with a 5-cm tail, and it weighs about 39 g (1.4 oz).They are found on moist rocky slopes in eastern Canada and the northeastern United States. They make runways through the surface growth and shallow burrows. They are usually found in small colonies.They feed on grasses, mosses, underground fungi and berries (especially bunchberry), and also sometimes on caterpillars. Predators include hawks, owls, snakes and small carnivorous mammals.The female vole has two or three litters of four to seven young. They are active year-round, mainly during the day, but are rarely seen. It has been designated as a species of concern in some parts of its range.
