How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • The mass of a glucose molecule: This is a representative comparison value; individual specimens or conditions can vary.

Mass is distinct from weight: an object’s mass stays the same as gravity changes.
