What weight does our weighing machine show?Is it the mass or weight(mg)?
Mass is in kg/ slugs. Weight is in Newtons/ Pounds...so whichever one is written is what it "shows".
It measures your weight (mg) however, and then either displays that or assumes g and converts it for you.
A spring balance will only register your weight (force). A true balance or a steelyard will compare the mass of your test object with a standard mass, irrespective of local g.
A weighing 'machine' such as bathroom scales indicates the force between the ground and your feet. If you are not accelerating vertically this is the force of gravity on you, this is what is usually called your 'weight'
On the balance , you have mass(kg) but many people say weight which is scientifically wrong.
Unlike your mass , your weight can vary whether it's on the moon or earth or any planet due to the fact that gravity varies.
