Human arm
The human arm is the upper limb of the body, extending from the shoulder to the hand and enabling a wide range of movement and manipulation.

Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.
A little perspective
The one-arm mass in a 70 kg model of the human arm is about 1.15 times 3 kilograms.

Mass: 3 kg; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Human arm
One-arm mass in a 70 kg model: 3.46 kg; representative model; range 2.5 kg–4.5 kg.
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.

- Comparing
- Mass ↔ One-arm mass in a 70 kg model
- Relative size
- The one-arm mass in a 70 kg model of the human arm is about 1.15 times 3 kilograms. The one-arm mass in a 70 kg model of the human arm is approximately 15.3% greater than 3 kilograms.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 3.46 kg for the one-arm mass in a 70 kg model of the human arm; the recorded range is 2.5 kg–4.5 kg.
- The one-arm mass in a 70 kg model of the human arm: 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.
