Bar length measures mass, not physical size.

A little perspective

The one-leg mass in a 70 kg model of Human leg is about 1.03 times the mass of 25 pounds.

Measurements, assumptions & sources +

25 pounds

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

NIST — SI conversion factors

Human leg

One complete leg in a defined 70 kg adult model: 1.0 m from hip to heel and 11.68 kg, using published thigh, shank and foot mass fractions. This is a comparison model, not a population average.

de Leva — Adjustments to Zatsiorsky-Seluyanov segment inertia parameters

The marked one-leg mass in a 70 kg model is calibrated. Unmeasured illustration details are representative.

Relative size
Human leg is larger on this measurement by a factor of about 1.03. Human leg's selected measurement is approximately 3% greater than 25 pounds's.

How to read the visual

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

  • Human leg uses a 11.68 kg central value within a recorded range of 9 kg–14 kg.
  • Human leg is labelled representative model; 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.
