Things measured in grizzly bears
A grizzly bear weighs about 130–360 kg, which makes it a usable informal unit — "three elephants" lands where a raw figure in kg does not. Every comparison below is computed from a sourced figure rather than an invented average.

Why informal units work
Absolute figures fail because most people have no calibrated sense of a kilogram above about the weight of a shopping bag, or of a metre above their own height. A familiar object supplies that calibration by borrowing it from something already known — which is the same reason a scale bar on a map beats a stated ratio, and why "the size of Wales" persists in journalism despite being useless to anyone who has not been there.
The figure for one grizzly bear is itself a range rather than a constant — see its own page for the spread. These comparisons are for intuition, not measurement.
Common questions
