By weight · Order from lightest to heaviest.

1. A black garden ant worker 1.5 mg

   Ants can carry 10 to 50 times their own body weight — the square-cube law makes tiny bodies absurdly strong for their size.

2. A single drop of water 50 mg

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

3. A brilliant-cut one-carat diamond 200 mg

   The carat unit comes from carob seeds, which ancient gem traders used as counterweights on their balance scales.

4. 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.

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 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.
