By weight · Order from lightest to heaviest.

1. A black garden ant worker 1.5 mg

   Ants can carry 10 to 50 times their own body weight — the square-cube law makes tiny bodies absurdly strong for their size.

2. A 16-inch MacBook Pro 2.2 kg

   Apple's obsession with grams runs deep: the original 1989 Macintosh Portable weighed more than three of these.

3. An average adult human, averaged across the whole world 62 kg

   Researchers computed this from global census data; North America's average is about 20 kg heavier than Asia's.

4. An adult male giraffe 1.2 t

   A giraffe's heart generates about double the blood pressure of most mammals to push blood two meters up its neck to the brain.

5. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

6. An M1 Abrams main battle tank 62 t

   Despite the bulk it tops 65 km/h, powered by a jet-style gas turbine engine that can run on almost any fuel.
