By weight · Order from lightest to heaviest.

1. A ruby-throated hummingbird 4 g

   It crosses the Gulf of Mexico nonstop — about 800 km — burning nearly half its body fat in a single 20-hour flight.

2. A kiwi fruit 75 g

   Originally China's 'mihoutao', it was rebranded by New Zealand exporters in 1959 after their flightless national bird.

3. A whole wheel of Parmigiano-Reggiano cheese 38 kg

   Italian banks accept aging Parmesan wheels as loan collateral, storing thousands of them in climate-controlled vaults.

4. A front-loading washing machine 76 kg

   Much of the heft is a deliberate concrete counterweight — without it, the spin cycle would walk the machine across your floor.

5. The Antonov An-225 Mriya cargo plane at maximum takeoff weight 640 t

   The heaviest aircraft ever built was destroyed in Ukraine in 2022; 'Mriya' means 'dream' in Ukrainian.

6. The RMS Titanic 52K t

   Each of her giant anchors needed a team of 20 horses to haul through the streets of Belfast to the shipyard.
