1. The width of a human hair 0.1 mm

   Hair width is so consistent it was once a unit of precision; forensic labs still match hairs to within fractions of this.

2. A grain of rice 7 mm

   Rice feeds more than half the planet, and a single plant can yield thousands of these grains.

3. A roasted coffee bean 8.5 mm

   A coffee 'bean' is actually the seed of a cherry-like fruit that grows on shrubs near the equator.

4. A standard wine bottle 30 cm

   The 750ml bottle size is often linked to the lung capacity of a glassblower's single breath.

   A tiger's roar can be heard up to three kilometres away and carries frequencies low enough to paralyse prey with fear.
