Are you sure that you saw the weight of something being specified rather than its mass?
Since gravitational mass and inertia mass are equivalent, one can measure the mass of something by weighing it (and converting considering the gravitational field).
A scale for body weight on earth is not intended to report the force that your body produces in earth's gravitational field, but the mass of your body. Hence the unit used is "kg" not "N".
I suspect that in all your observations the unit "kg" is correctly used to express the mass of something.
The imprecision is only in everday language where people do not consider other gravitational fields (e.g., that on the moon) and therefore do not distinguish between weight and mass. That unawareness of the difference between these concepts probably exists just as much in countries that do not use metric systems, if only through lay people pretty much never using the unit for mass.
Originally posted by tuco So what units does the typical layman say in your area when they are talking about a moment (torque). Kilogram-meter? If they say newton-meter than I'd really be blow away by the inconsistency.
They use Newton-meter, of course, since only a force is involved.
Kilogram-meter, would only make sense if the force were created by a mass, which is typically not the case.
