By weight · Order from lightest to heaviest.
- A single kernel of corn 300 mg
Each kernel is botanically a complete fruit, and a typical ear carries an even number of rows — most often sixteen.
- 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 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.
- 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.
- An adult giant panda 110 kg
Pandas spend up to 14 hours a day eating bamboo because they digest only about a fifth of what they swallow.
- A full-size kitchen refrigerator 135 kg
Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.
