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
