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 one-euro coin 7.5 g

   Its two-metal design is not just style — the distinct layers give vending machines an electromagnetic signature to verify.

3. A full backyard barbecue propane tank 17 kg

   The familiar grill tank stores propane as a liquid; on a hot summer day the pressure inside can roughly triple.

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 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 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.
