By weight · Order from lightest to heaviest.

1. A single grain of table salt 60 µg

   Salt crystals are near-perfect cubes because sodium and chloride ions lock into a rigid lattice — about a million grains fit in one cup.

2. A single drop of water 50 mg

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

3. A AAA alkaline battery 11.5 g

   Despite the tiny package, a fresh AAA stores enough energy to hoist an adult human several meters into the air.

4. A round loaf of sourdough bread 800 g

   Some sourdough starters are family heirlooms over 150 years old, kept alive by daily feedings of flour and water.

5. An average adult domestic cat 4.2 kg

   Cats purr at frequencies between 25 and 150 Hz — a range some studies suggest can promote bone and tissue healing.

6. A Tesla Model 3 1.8 t

   Around a quarter of the car's entire mass is its battery pack, mounted in the floor for a racing-car center of gravity.
