SortStack #287 — 2027-03-23

By weight · Order from lightest to heaviest.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.
