By weight · Order from lightest to heaviest.

1. A house sparrow 28 g

   House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

2. A stick of butter 113 g

   US butter sticks come in two shapes: the stubby 'Western' stick exists because West Coast dairies bought different molds.

3. A standard Good Delivery gold bar, the kind in bank vaults 12.4 kg

   Smaller than a brick yet heavier than most pet dogs — gold is so dense this bar would fit in a shoebox with room to spare.

4. An upright piano 220 kg

   Inside is a cast-iron plate holding strings at a combined tension of roughly 18 tonnes of pull.

5. An adult male white rhinoceros 2.3 t

   The 'white' is likely a mistranslation of the Dutch 'wijd', meaning wide — describing its broad, lawn-mowing mouth.

6. 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.
