By weight · Order from lightest to heaviest.

1. A common housefly 12 mg

   Houseflies beat their wings around 200 times per second, which produces their signature buzzing pitch near the note F.

2. A sheet of A4 printer paper 5 g

   A-series paper is metric by design: every size is exactly half the one above it, all sharing the same elegant proportions.

3. An adult human brain 1.4 kg

   It is about 2% of your body weight yet burns roughly 20% of your energy — mostly just keeping billions of neurons ready to fire.

4. The Liberty Bell 943 kg

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.

5. An adult male Asian elephant 4 t

   You can tell it from its African cousin by the much smaller ears and the twin domes on its forehead.

6. An adult male sperm whale 45 t

   Its clicks reach about 230 decibels — the loudest animal sound on Earth — and a third of its body is one giant sonar-focusing nose.
