Endocranial Volume

Volume of the cranium, including that of the brain and meninges. The standard unit of measurement is the cubic centimeter (cm3). Some prosimians have brains that are about the volume of a walnut (50 cm3), monkeys about the volume of a small apple (200 cm3), and apes about the volume of a large orange (500 cm3), while humans have brains that are about the volume of a cantaloupe melon (1350 cm3). In primates, the endocranial volume is approximately 104% of brain mass.
