By weight · Order from lightest to heaviest.

1. 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.

2. A standard car tire, without the rim 10 kg

   About a quarter of a tire's mass is not rubber at all — it is steel belts and textile cord hidden inside the carcass.

3. A giant Pacific octopus 30 kg

   It can squeeze its entire body through any gap larger than its beak — the only hard part it owns.

4. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

5. The RMS Titanic 52K t

   Each of her giant anchors needed a team of 20 horses to haul through the streets of Belfast to the shipyard.

6. The Great Pyramid of Giza 5.8M t

   Roughly 2.3 million stone blocks were stacked over about 20 years — averaging a block placed every few minutes of every workday.
