By weight · Order from lightest to heaviest.

1. A sheet of A4 printer paper 5 g

   A-series paper is metric by design: every size is exactly half the one above it, all sharing the same elegant proportions.

2. 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.

3. An adult male African bush elephant 6 t

   The largest land animal walks almost silently — its foot pads expand and absorb sound like cushioned trainers.

4. An adult Tyrannosaurus rex 8.5 t

   'Sue', the most complete T. rex ever found, sold at auction in 1997 for $8.4 million and now has its own social media accounts.

5. A Boeing 777-300ER airliner at maximum takeoff weight 351.5 t

   Each of its GE90 engines is so wide that a Boeing 737 fuselage could very nearly fit inside the cowling.

6. The Burj Khalifa in Dubai 500K t

   The world's tallest building is tall enough to watch the sunset at the base, ride the elevator up, and watch it set again.
