Bar length measures mass, not physical size.

A little perspective

The mass of 10 pounds is about 1.31 times the one-arm mass in a 70 kg model of Human arm.

Measurements, assumptions & sources +

10 pounds

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

NIST — SI conversion factors

Human arm

One complete arm in a defined 70 kg adult model: 75 cm from shoulder to fingertip and 3.46 kg, using published upper-arm, forearm and hand mass fractions. This is a comparison model, not a population average.

de Leva — Adjustments to Zatsiorsky-Seluyanov segment inertia parameters

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

Why these numbers?

The visual compares mass with one-arm mass in a 70 kg model. The records below preserve each value’s basis and caveats.

Comparing: Mass ↔ One-arm mass in a 70 kg model
Relative size: 10 pounds is larger on this measurement by a factor of about 1.31. 10 pounds's selected measurement is approximately 31.1% greater than Human arm's.

How to read the visual

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

Human arm uses a 3.46 kg central value within a recorded range of 2.5 kg–4.5 kg.
Human arm is labelled representative model; treat the displayed value as a comparison anchor rather than false precision.
