100 kg of goose feathers or 100 kg of mass and why[?]

A 150 lb man would weight about 25 lb on the moon. But he would still mass 150 lb.

Weight is a force and should be measured in Newtons, not in lb.
The SI unit for mass is Kg

The SI unit for weight may be the Newton, but it's perfectly legit to use the pound (lb) for weight. If someone uses the pound to describe an object's weight and not the Newton, so be it, there's nothing objectable to that. You can very easily switch between pounds and Newtons with a simple conversion, anyways.

The SI unit for Mass is Kg, the Imperial unit is the pound.
The SI unit for weight is the Newton, the Imperial unit is the pound-force, not the pound.

Earth pounds or Moon pounds?

That's if he weighed 150lb on earth...who said anything about what he weighs on earth?A 150 lb man would weight about 25 lb on the moon. But he would still mass 150 lb
In the US we do - layman and engineers alike. Heck, if you make your bathroom scale read in kg, its using kg as weight!You can't use the pound for both mass and weight - they are completely different quantities!

Mass refers to the amount of matter an object contains, while weight is the measure of the force of gravity acting on an object's mass. In other words, mass is a constant property of an object, while weight can vary depending on the strength of the gravitational pull.
When comparing mass, it is important to consider the density of the objects. While both 100 kg of goose feathers and 100 kg of mass have the same value in terms of mass, their volume and density will differ. This means that the 100 kg of goose feathers will take up more space and have a lower density compared to the 100 kg of mass.
Understanding mass is crucial in various scientific fields, such as physics and chemistry. Mass is a fundamental property of matter and plays a role in many physical and chemical processes. It is also an essential factor in determining the behavior of objects under the influence of forces, such as gravity and friction.
Mass is typically measured using a balance or scale. These tools use the principle of equilibrium to determine the mass of an object by comparing it to a known mass. The most common unit of mass is the kilogram (kg) in the metric system, but other units such as pounds (lb) and grams (g) are also used.
Yes, mass can be converted into different units depending on the system of measurement used. For example, in the metric system, 1 kg is equivalent to 1000 g, while in the imperial system, 1 lb is equal to 16 oz. It is important to note that the mass itself does not change, only the unit of measurement being used.
