By weight · Order from lightest to heaviest.

1. A single drop of water 50 mg

   Pharmacists standardized the 'drop' centuries ago: twenty drops make roughly one milliliter.

2. A western honeybee worker 100 mg

   To make one jar of honey, a hive's bees collectively fly a distance equal to about three orbits of the Earth.

3. The Hope Diamond 9.1 g

   The famous blue gem glows an eerie red-orange for minutes after exposure to ultraviolet light — a quirk of trace boron inside.

4. An adult house mouse 19 g

   Male mice sing ultrasonic courtship songs too high-pitched for humans to hear, with repeated phrases like birdsong.

5. A regulation NBA basketball 620 g

   Each ball is covered in tens of thousands of tiny pebbled bumps, a texture invented so sweaty hands could keep their grip.

6. An adult male grizzly bear 270 kg

   Before hibernation a grizzly can pack on more than a kilogram of fat per day, entering the den far heavier than in spring.
