By weight · Order from lightest to heaviest.

1. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

2. A single sesame seed 3 mg

   Sesame is one of humanity's oldest oil crops, domesticated in South Asia more than 3,000 years ago.

3. 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.

4. A stick of butter 113 g

   US butter sticks come in two shapes: the stubby 'Western' stick exists because West Coast dairies bought different molds.

5. 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.

6. 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.
