SortStack #3045 — 2034-10-10

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. 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.

  3. A one-euro coin 7.5 g

    Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

  4. A liter of water 1 kg

    The kilogram was originally defined in the 1790s as the mass of exactly this much water — the tie was only fully broken in 2019.

  5. 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.

  6. A fully equipped fire engine 18 t

    Around 2,000 liters of onboard water account for a chunk of the heft — plus ladders, hoses, and hydraulic rescue tools.
