By weight · Order from lightest to heaviest.
- A single grain of table salt 60 µg
Salt crystals are near-perfect cubes because sodium and chloride ions lock into a rigid lattice — about a million grains fit in one cup.
- A monarch butterfly 500 mg
Despite weighing less than a paperclip, monarchs migrate up to 4,800 km from Canada to mountain forests in central Mexico.
- An Etruscan shrew, the world's smallest mammal by mass 1.8 g
Its heart beats up to 1,500 times a minute, and it must eat about twice its body weight in insects every single day.
- A AAA alkaline battery 11.5 g
Despite the tiny package, a fresh AAA stores enough energy to hoist an adult human several meters into the air.
- A kiwi fruit 75 g
Originally China's 'mihoutao', it was rebranded by New Zealand exporters in 1959 after their flightless national bird.
- A classic yellow American school bus 11 t
The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.
