how much does a head weigh
The weight of the human head is 8-12 pounds while the average weight of the helmet used in our sample is 2.7 pounds.. 3.6kg-5.4kg. The typical mass of a human head is about 5 kilograms, significantly larger than what the movie Jerry Maguire suggests, a mere 3600 grams. This result probably puts most heads at roughly seven percent of the person's body mass.
