Bar length measures force in newtons. Mass and local gravity determine weight.

A little perspective

The weight of a 70 kg person is about 1.37 times 500 newtons.

Measurements, assumptions & sources +

500 newtons

Weight: 500 N; definition.

Weight is gravitational force. An object keeps its mass while its weight changes with local gravity.

NIST — SI conversion factors

Weight of a 70 kg person

Weight: 686.5 N; example.

A 70 kg person at standard Earth gravity. This is force in newtons, not a different mass.

Defined examples — our methodology

The marked weight 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.

  • The weight of a 70 kg person: This is an illustrative comparison value, not a claim that every example is the same.

Weight is gravitational force; the same mass weighs differently where gravity changes.
