5 stone
Mass: 31.75 kg; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Human-powered aircraft
Approximate empty mass: 32 kg; representative; range 30 kg–35 kg.
A Gossamer Albatross-style human-powered aircraft with NASA's quoted 94 ft (28.7 m) span, approximately 10 m length, 32 kg empty mass and a representative 5 m/s flight speed. The pilot is excluded from empty mass.
The marked approximate empty mass is calibrated. Unmeasured illustration details are representative.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 32 kg for the empty mass of a human-powered aircraft; the recorded range is 30 kg–35 kg.
- The empty mass of a human-powered aircraft: This is a representative comparison value; individual specimens or conditions can vary.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
Mass is distinct from weight: an object’s mass stays the same as gravity changes.
