- Summary:
- understanding mass and mass as a force(weight)

Been thinking about mass today and came up with a question. Why is that objects on this earth describe its weight in Kg, g, mg, Mg? IE 2.2Lbs is 1Kg. So why do we name the 1Kg to be mass, but the 2.2Lbs we call weight. Both have to be a unit of force if there is a conversion factor between the two numbers. if 1Kg IS 2.2 lbs, then 1Kg is also considered weight because a 1.3Kg jar of honey is NOT 1.3Kg on the moon or anywhere else.

we know mass to be what we are made of, atoms, etc. so when and how decided it to be a unit of force?

so how do we know what really is. How do i know what my mass really is? Some say my mass is 104Kg, but that is purely based on a gravitational constant of 9.81.

so how do we really measure mass?

thanks
