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 McDonald's Big Mac 220 g

   The Economist uses Big Mac prices to compare currency values worldwide — the famously tongue-in-cheek 'Big Mac Index'.

3. A regulation NBA basketball 620 g

   Each ball is covered in tens of thousands of tiny pebbled bumps, a texture invented so sweaty hands could keep their grip.

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 Eiffel Tower 10.1K t
