By weight · Order from lightest to heaviest.

1. 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.

2. A compact disc 15 g

   A CD's spiral data track is less than a micrometer wide and would stretch about five kilometers if unwound.

3. An iPhone 15 Pro 187 g

   Its titanium frame is the same alloy grade used in spacecraft and joint implants, trimming heft from earlier steel models.

4. A classic yellow American school bus 11 t

   The exact yellow is a legal standard from 1939, chosen because black lettering on it reads fastest in dim morning light.

5. An M1 Abrams main battle tank 62 t

   Despite the bulk it tops 65 km/h, powered by a jet-style gas turbine engine that can run on almost any fuel.

6. The Motherland Calls statue in Volgograd, Russia 8K t

   Twice the height of the Statue of Liberty, sword included, she is not anchored to her base — held in place by gravity alone.
