Measurements, assumptions & sources +

5 kilometres per hour

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Venetian gondola

A traditional Venetian gondola approximately 10.85 m long and 600 kg unladen, shown at a defined 1.5 m/s cruising pace. Handmade boats vary slightly; hull length excludes the removable ferro and raised oar.

Encyclopaedia Britannica — Gondola

The marked defined cruising speed is calibrated. Unmeasured illustration details are representative.

Speed ↔ Defined cruising speed
Relative size
Venetian gondola is larger on this measurement by a factor of about 1.08. Venetian gondola's selected measurement is approximately 8% greater than 5 kilometres per hour's.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Venetian gondola uses a 1.5 m/s central value within a recorded range of 1 m/s–2 m/s.
  • Venetian gondola is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.
