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 16-inch MacBook Pro 2.2 kg

   Apple's obsession with grams runs deep: the original 1989 Macintosh Portable weighed more than three of these.

3. An adult male western lowland gorilla 160 kg

   Silverbacks are several times stronger than a fit human, yet they eat almost nothing but plants and the occasional termite.

4. An adult blue whale 140 t

   The largest animal ever known has a heart the size of a small car, and its calves gain roughly 90 kg per day on milk alone.

5. The International Space Station 420 t

   Assembled over 42 flights, it circles Earth 16 times a day at 28,000 km/h, so its crew sees 16 sunrises daily.

6. The Golden Gate Bridge 805K t

   Its two main cables contain enough wire to circle the Earth three times, and painting crews never actually finish — they cycle forever.
