A little perspective

The mass of 1 pound is about 1.01 times the defined broom mass of Curling broom.

Measurements, assumptions & sources +

1 pound

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

NIST — SI conversion factors

Curling broom

A defined competition-style curling broom 1.22 m long and weighing 450 g. Handle length and head construction vary; the World Curling rules chiefly govern the sweeping-head fabric.

Mass ↔ Defined broom mass
Relative size
1 pound is larger on this measurement by a factor of about 1.01. 1 pound's selected measurement is approximately 0.798% greater than Curling broom's.

How to read the visual

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

  • Curling broom uses a 450 g central value within a recorded range of 350 g–600 g.
  • Curling broom is labelled defined specimen; 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.
